Firefox Shortcuts: The Complete 2026 Keyboard Guide

Firefox has a shortcut for nearly everything you’d otherwise reach for the mouse to do, and most of them haven’t changed in years — learn one and it keeps working. This guide covers the Firefox shortcuts worth memorizing: reopening a tab you just closed, opening a private window, jumping between tabs, managing bookmarks, and getting your whole session back after a crash. It also includes a short starter list if you’d rather learn ten and move on with your day than memorize all thirty at once. Every fact here comes straight from Mozilla’s own support pages, current as of September 2026.

One thing worth saying up front: a shortcut is only a memory aid for browsing you’re still actively doing. If your laptop dies mid-session, or Firefox never gets the chance to write its session file, no keyboard combination brings that back. We’ll show you the built-in Firefox tools that help with that, and where they run out, where BelayTab picks up.

Quick Answer: Firefox Shortcuts by Task

The shortcut you need depends on what you’re trying to do, and the table below covers the Firefox shortcut keys people search for most, side by side for Windows/Linux and Mac.

Notice that “restore previous session” doesn’t have a dedicated key combination. It lives in the History menu, and we’ll walk through exactly where a little further down. Everything else in that table is a straight key combo you can build into muscle memory within a week or two of using it deliberately instead of reaching for the mouse.

A few of these are worth a second look because people assume they behave like a competing browser’s version and get tripped up. Ctrl+Tab, for instance, doesn’t move left to right through your tabs. It jumps to whichever tab you used most recently, which feels strange until you get used to it. And Restore Previous Session isn’t always visible: if Firefox is already set to reopen your tabs automatically on launch, that menu item disappears entirely, because there’s nothing left for it to do manually.

Which 10 Firefox Shortcuts Should You Learn This Week?

Learn these ten first, because they cover the vast majority of what you do in a browser in a normal day, and none of them require you to remember a menu path. Trying to memorize all thirty-plus shortcuts Firefox supports at once is how people give up after day two; ten is realistic.

1. Ctrl+T — New tab. The one you’ll use the most, by far.
2. Ctrl+W — Close tab. Faster than clicking the small x, especially on a trackpad.
3. Ctrl+Shift+T — Reopen closed tab. The one that saves you from “wait, why did I close that.”
4. Ctrl+Tab — Switch to your last-used tab. Faster than hunting across a crowded tab bar.
5. Ctrl+9 — Jump to your last tab. Handy for pinned tabs or a reference tab you keep open at the end of the row.
6. Ctrl+H — History sidebar. Faster than the menu when you’re hunting for a page you visited a few days ago.
7. Ctrl+D — Bookmark this page. One press instead of a mouse trip to the star icon.
8. Ctrl+F — Find on page. Essential for long articles or documentation.
9. Ctrl+Shift+P — New private window. For anything you don’t want sitting in regular history.
10. Ctrl+Shift+N — Reopen closed window. The one people forget exists until they need it badly.

If you only take one thing from this list, make it Ctrl+Shift+T. It’s the shortcut with the best ratio of “how often you’ll need it” to “how annoying it is to do manually,” since clicking back through History to find one closed tab takes several times longer than a single key combination. Once that one’s automatic, add Ctrl+Tab and Ctrl+9 next — together they cover most tab navigation without ever touching the mouse. The rest come naturally once those three are muscle memory.

What Are the Essential Firefox Keyboard Shortcuts?

Firefox’s essential shortcuts fall into four groups (tabs, windows, bookmarks, and history) and the table below lists the fuller set Mozilla documents, so you don’t have to hunt across several help pages to find one you half remember.

This is Mozilla’s official keyboard shortcuts list, reformatted so the ones people actually search for aren’t buried under rarely used ones. A few, like Reader Mode and the bookmarks sidebar, don’t exist in every browser, which is worth knowing if you split time between Firefox and something else and keep expecting the same combo to work everywhere.

It’s also worth noticing what isn’t on this list: there’s no built-in shortcut for things like reopening a whole closed window’s worth of tabs as a saved set, jumping to a specific past session, or searching across every tab you have open at once. Firefox handles some of that through its menus instead of a key combination, and some of it, as you’ll see later, it doesn’t handle at all once a session is truly gone.

How Do You Reopen a Closed Tab in Firefox?

Press Ctrl+Shift+T on Windows or Linux, or Cmd+Shift+T on Mac, and Firefox reopens the tab you just closed, exactly where it was, scroll position and all. Press it again and it works backward through more tabs, in the order you closed them — handy after you accidentally close three tabs while cleaning up a window, or fat-finger the close button on the wrong one.

If you’d rather pick a specific tab instead of cycling through them one press at a time, the menu offers more control and lets you see exactly what you’re about to reopen before committing to it.

There’s one catch worth knowing before you rely on this daily: Ctrl+Shift+T only works if history is turned on. If you’ve set Firefox to never remember history, the shortcut has nothing to pull from and simply does nothing, no error message, no prompt — the tab is just gone, since Firefox was told not to keep a record of it in the first place.

If you close tabs constantly and want a deeper dive into the mechanics — including what happens when history is disabled and how other browsers handle the same problem — our guide to how to reopen closed tabs in any browser covers the edge cases for every major browser, not just Firefox.

How Do You Open a Private Window in Firefox?

Press Ctrl+Shift+P (Cmd+Shift+P on Mac) to open a new Private Window, or right-click any link and choose “Open Link in New Private Window” if you only need one page private rather than a whole browsing session. You’ll know it worked because a purple mask appears at the top of the window — a deliberate visual cue so you don’t forget which window you’re in.

Private Browsing doesn’t save visited pages to History, form or search-bar entries, or offline cached content, and its cookies live only in memory, separate from your normal cookies, until the last private window closes. New bookmarks or passwords you save while in a private window are the exception. Those stick around permanently, which surprises people who assume “private” means nothing persists. It’s also worth knowing this mode isn’t anonymous: your internet provider, employer, or the sites themselves can still see what you’re visiting, and it offers no protection against keyloggers or spyware already on your device.

Closed private tabs don’t come back. Private Browsing windows are never restored. That session is deleted the moment you close it, by design. Ctrl+Shift+T won’t bring back a private tab, and neither will Restore Previous Session, because Firefox never kept a record of it in the first place.

Starting with Firefox 151, there’s also a fire-icon “End/Clear Private Session” button next to the address bar that instantly wipes the current private session and opens a fresh one without closing the browser — useful on a shared computer between visitors, or when you want a clean slate mid-session without quitting Firefox entirely. And if you rely on a particular extension while browsing privately, note that extensions don’t run in private windows by default; you have to grant that permission at install time, via the “Run in Private Windows” checkbox, or later through Add-ons and Themes > Extensions. For more on how private tabs behave day to day, see our Firefox private tabs guide.

How Do You Manage Bookmarks with Firefox Keyboard Shortcuts?

Press Ctrl+D (Cmd+D on Mac) to bookmark whatever page you’re on, Ctrl+B to open the bookmarks sidebar, and Ctrl+Shift+B to show or hide the Bookmarks Toolbar. For the full library view with folders and search, use Ctrl+Shift+O (Cmd+Shift+O on Mac), which opens a proper window rather than a slim sidebar — worth it once your bookmarks folder gets past a couple dozen entries.

That Library window is also where backups happen, and it’s worth knowing the difference before you need it in a hurry. Under Import and Backup, “Export Bookmarks to HTML” gives you a bookmarks.html file meant for moving bookmarks to another browser or computer, while “Backup” creates a bookmarks-<date>.json file meant only for restoring inside Firefox itself. They aren’t interchangeable, and picking the wrong one when you need it is a common frustration. Firefox also keeps its own automatic backups without you doing anything: it stores the last 15 dated backups in a bookmarkbackups folder inside your profile, and you can roll back to any of them from Import and Backup > Restore. Just know that restoring overwrites your current bookmarks entirely, so it’s not something to click casually if you’ve added anything new since that backup was made.

Coming from Chrome, Edge, or Safari, the Import Data wizard under Settings > General handles bookmarks, saved logins, history, and form history in one pass, landing the imported bookmarks in a folder inside your Bookmarks Toolbar or menu rather than merging them loose into your existing structure. If the toolbar itself is the part you’re unsure about (how to show it, hide it, or keep it tidy) our bookmarks bar guide covers showing, hiding, and organizing it across browsers, not just Firefox.

How Do You Switch Between Open Tabs in Firefox?

Press Ctrl+Tab to cycle through your tabs in the order you most recently used them, not their left-to-right position on the tab bar — which takes some getting used to if you expect it to move sequentially like it does in some other apps. Hold Ctrl and keep tapping Tab to keep moving through the list, or add Shift to go backward through it.

For jumping straight to a specific tab, Ctrl+1 through Ctrl+8 (Cmd+1 through Cmd+8 on Mac) jump to that tab’s position counting from the left, and Ctrl+9 always jumps to your last tab, no matter how many you have open. That last one is the shortcut worth memorizing first. It’s the fastest way back to whatever you opened most recently, like the window with your flight booking in it, right after you got pulled into forty research tabs for a work deadline and lost track of where you started.

These shortcuts are genuinely useful once you have a lot open, but they only help you navigate tabs that are already there. They don’t do anything to protect those tabs if the window closes unexpectedly, gets accidentally clicked shut, or the computer restarts for an update. That’s a different problem entirely, and one we’ll come back to shortly. Position-based shortcuts like Ctrl+1 also shift under you the moment you reorder tabs by dragging one, which is worth remembering if you rely on a specific tab always being “Ctrl+3.”

How Do You Restore Your Whole Browsing Session in Firefox?

Open the menu button, go to History, and click Restore Previous Session to bring back every tab and window from your last browsing session in one action. If you don’t see that option, it usually means Firefox is already set to restore your tabs automatically on every launch, which makes the manual option redundant.

That automatic behavior lives in a separate setting, and it’s worth turning on if you don’t want to remember the manual step every single time you open the browser.

Behind the scenes, Firefox writes your open tabs to a file called sessionstore.jsonlz4 in your profile folder, but only when it closes properly — a hard crash can skip that step entirely. While it’s running, Firefox keeps rolling backups in a sessionstore-backups subfolder: the most recent live copy, the previous live copy, and a clean copy saved from the last session that loaded successfully. If a crash prevents auto-restore from working, Firefox shows a dedicated Restore Session page where you choose which tabs to bring back, sometimes described informally as the “well, this is embarrassing” page. You can find your profile folder through about:support or about:profiles if you ever need to dig into those files directly — our Firefox session reader can help make sense of what’s in there without touching the original files. For a deeper walkthrough of every scenario, see Firefox restore last session and, if crashes are the actual problem, Firefox keeps crashing, which covers Mozilla’s recommended fix order in detail.

Why Do Some Firefox Shortcuts Stop Working?

Two documented reasons cover most cases: the combination is already claimed by your operating system, or the shortcut depends on a setting you’ve turned off. Ctrl+Shift+T is the most common example of the second one. It needs history enabled under Settings > Privacy & Security > History, set to either remember history or use custom settings that still track it.

If you’ve set Firefox to never remember history at all, for privacy reasons, you’ve effectively turned off the safety net that shortcuts like reopening closed tabs and Restore Previous Session both depend on. That’s a reasonable trade-off if privacy matters more to you than convenience, but it’s worth knowing you’re making it — the shortcut isn’t broken, it just has nothing to work from, the same way a search box returns nothing if you never typed anything into it.

Test in Troubleshoot Mode if a shortcut seems stuck. If a shortcut behaves oddly across the board, Mozilla’s Troubleshoot Mode (menu > Help > Troubleshoot Mode, or hold Shift while launching Firefox) temporarily disables all extensions, switches to the default theme, and turns off hardware acceleration. If the shortcut works there, an extension or setting is the cause.

Before assuming a shortcut is broken, it’s also worth checking whether another app on your system uses the same combination — window managers, screenshot tools, and some corporate lockdown software are common culprits, and Firefox has no way to override them since the operating system intercepts the keypress first. If Troubleshoot Mode doesn’t explain it either, Mozilla’s broader crash and stability guidance covers the same fix order for related problems: update Firefox, disable extensions and hardware acceleration, refresh Firefox to reset it to a default state, create a new profile if a refresh doesn’t help, and check for malware as a last resort before assuming it’s a Firefox bug.

How Do Firefox Shortcuts Compare to Chrome’s?

If you’ve switched from Chrome, several Firefox shortcuts will already feel familiar since both use the same basic patterns for tabs and windows — new tab, close tab, and reopening a closed tab all sit on recognizable combinations you won’t have to relearn from scratch. Rather than guess at Chrome’s exact key combos here, our Chrome shortcuts guide lays out its full list if you want a side-by-side reference while your muscle memory catches up.

Where Firefox pulls ahead is in a handful of shortcuts that Chromium-based browsers simply don’t have a direct equivalent for, built around features that are unique to Firefox itself rather than the browser engine underneath.

• Reader Mode. Ctrl+Alt+R or F9 strips a page down to just its text and images, a feature built into Firefox itself.
• Bookmarks Sidebar. Ctrl+B opens bookmarks alongside your page without leaving it, rather than as a separate tab.
• Troubleshoot Mode. Holding Shift at launch isolates extension and hardware-acceleration problems in one step.

None of this makes one browser strictly better for keyboard users. It mostly comes down to which shortcuts you’ve already built into muscle memory and whether a feature like Reader Mode or a bookmarks sidebar fits how you browse. If you’re trying to decide between the two browsers more broadly rather than just their shortcuts, Chrome vs Firefox in 2026 covers the bigger picture, including sync, extensions, and privacy defaults.

What Should You Do When a Shortcut Can’t Bring Your Tabs Back?

Reach for BelayTab, because at that point Firefox has nothing left to give a shortcut to work with. Shortcuts and Session Restore both depend on Firefox itself having a record of your tabs — if you reinstalled the browser, switched to a new computer, or closed a private window, that record simply doesn’t exist, and no key combination changes that, no matter how many times you press it.

BelayTab is a free browser extension that saves your open tabs as named sessions you can restore later, with no account and no limits on sessions or tabs. It takes automatic snapshots of every window every 5 minutes and whenever a window closes, keeps the last 20 versions of each session so restoring never overwrites your history, and holds deleted sessions in a 30-day trash instead of deleting them outright. Everything shows up in one Recovery screen alongside the browser’s own recently closed windows, so you’re not hunting through two different places to find one tab. It works on Firefox itself, along with Chrome, Edge, Brave, Opera, Vivaldi, Arc, and Safari on Mac — though it can’t reach into the browser’s history for anything closed before you installed it, and it doesn’t fix a crash or freeze on its own; it just makes sure the tabs survive one.
