Mozilla Firefox Keyboard Shortcuts
Firefox's shortcuts overlap heavily with Chrome's for the basics (Ctrl+T for new tab, Ctrl+W to close) since both browsers converged on similar conventions over years of competing for the same users, but several bindings diverge in ways worth knowing, particularly around bookmark management and Firefox's distinct approach to its developer tools and reader mode, neither of which Chrome has a direct equivalent for in the same form. Firefox's container tabs feature, which lets you isolate groups of tabs with separate cookie storage (useful for staying logged into multiple accounts on the same site simultaneously), has its own management shortcuts that Chrome doesn't have a direct native equivalent for without an extension. Because Firefox has historically emphasized user customization more than Chrome, its keyboard shortcut set can also be remapped through about:config or extensions in ways that go beyond what Chrome's more locked-down shortcut system typically permits.
Tabs Browsing
| Action | Windows | Mac | Description |
|---|---|---|---|
| Open new tab | Ctrl+T | Cmd+T | Opens a new tab showing Firefox's own start page, which surfaces pinned shortcuts, recent browsing, and (where enabled) Pocket-recommended articles rather than a search-engine-branded page, with the address bar already focused, ready for a URL or search term the moment the new tab opens. |
| Reopen last closed tab | Ctrl+Shift+T | Cmd+Shift+T | Restores the most recently closed tab, and repeated presses continue walking back through Firefox's closed-tab history in order, drawing from the same session store that also survives an accidental full browser restart via History > Recently Closed Tabs, unlike some browsers where closed-tab memory is wiped once the app itself quits. |
| Bookmark current page | Ctrl+D | Cmd+D | Brings up Firefox's bookmark editor panel for whatever page is open, where beyond just picking a folder you can also attach searchable tags — a layer of organization noticeably deeper than the plain folder structure most other browsers stick to. |
| Toggle Reader View | F9 (or click the reader icon in address bar) | Cmd+Alt+R | Strips a compatible article page down to a clean, distraction-free text-only layout, a built-in feature Chrome doesn't offer natively without an extension. |
| Open new Private Window | Ctrl+Shift+P | Cmd+Shift+P | Spins up a fresh Private Browsing window that discards its history, cookies, and any typed form data the moment it closes; Firefox binds this to a different letter than Chrome's Incognito shortcut, which trips up plenty of people who use both browsers regularly. |
| Open new Container tab | Via Container icon menu (no default global key) | Via Container icon menu | Opens a new tab within an isolated cookie container, keeping a separate login session active in parallel with your normal browsing — a feature Chrome doesn't offer natively without a third-party extension. |
| Focus the address bar | Ctrl+L or Alt+D | Cmd+L | Jumps the cursor straight into the address bar with its existing text pre-selected, so you can immediately overwrite it with a new destination or query. |
| Toggle full-screen mode | F11 | Cmd+Ctrl+F | Expands the browser window to fill the entire screen, hiding tabs and toolbars, useful for distraction-minimal reading or presenting web content. |
Developer Tools
| Action | Windows | Mac | Description |
|---|---|---|---|
| Open Developer Tools | F12 or Ctrl+Shift+I | Cmd+Option+I | Opens Firefox's own Developer Tools panel, which shares conceptual similarity with Chrome DevTools but has distinct strengths, particularly its CSS Grid and Flexbox inspection overlays. |
| Toggle Responsive Design Mode | Ctrl+Shift+M | Cmd+Option+M | Firefox's equivalent of Chrome's device emulation toolbar, simulating various screen sizes for responsive testing — note the Mac shortcut differs from Chrome's identical-looking Cmd+Shift+M, since Firefox uses Option where Chrome uses Shift in the modifier combination. |
| View page source | Ctrl+U | Cmd+U | Opens the raw HTML source of the current page in a new tab, a quick way to check static markup without opening the full DevTools panel. |
Frequently Asked Questions
Why does Ctrl+Shift+P open Private Browsing in Firefox but Incognito uses a different shortcut in Chrome?
The two browsers simply standardized on different key combinations during their independent development — Firefox uses Ctrl+Shift+P (P for Private) while Chrome uses Ctrl+Shift+N (N for New incognito window). This is one of the most common points of confusion for people who regularly switch between both browsers, since muscle memory from one actively does something different in the other (Ctrl+Shift+P in Chrome opens the Command Menu/Print depending on context, not a private window).
Is Firefox's Reader View the same as Chrome's reading mode?
Conceptually similar but implemented independently — Firefox's Reader View (F9) is a long-standing native feature with its own distinct styling options (font, theme, text size) accessible directly within the reader view itself. Chrome's reading-focused features have historically been less consistently available natively and have varied more across versions and platforms.
Why does my Responsive Design Mode look different from Chrome's device toolbar?
Both tools serve the same general purpose — simulating different viewport sizes — but Firefox's implementation includes some distinct features like simulated touch events and a different set of preset device sizes, reflecting that the two browser engines built these tools independently rather than from a shared codebase.
What are container tabs and why would I use them over regular private browsing?
Container tabs isolate cookies and site data per container, letting you stay simultaneously logged into, say, two different accounts on the same website in separate tabs without them interfering with each other — unlike Private Browsing, which doesn't persist any session at all after closing, containers keep separate persistent logged-in sessions that you can return to.
Can I remap Firefox's default keyboard shortcuts?
Firefox doesn't expose a full built-in shortcut-remapping settings panel the way some applications do, but power users can customize certain bindings through about:config flags or via extensions built specifically for shortcut customization, offering more flexibility than Chrome's generally more fixed default shortcut set.
Does F11 fullscreen mode hide the same things on Mac as on Windows?
Behavior is broadly similar — both hide the tab bar and toolbars to maximize content space — though macOS's native fullscreen (triggered by Cmd+Ctrl+F) integrates with macOS's own Spaces/fullscreen app-switching system, while Windows' F11 fullscreen is a more contained in-app-only fullscreen toggle without that OS-level Spaces integration.
Does Firefox support syncing bookmarks and shortcuts across multiple devices?
Yes, Firefox Sync (tied to a free Firefox account) keeps bookmarks, history, saved passwords, and open tabs consistent across every device signed into the same account, though keyboard shortcut customizations made via about:config or extensions are generally per-device settings rather than something that syncs automatically.
Can I disable specific Firefox keyboard shortcuts I don't want active?
There's no single built-in settings panel for disabling individual default shortcuts, but certain extensions built for shortcut management can intercept and effectively neutralize specific bindings if a particular default conflicts with another workflow you rely on.
Can I quickly switch between Firefox's Multi-Account Containers with a keyboard shortcut?
Not directly — opening a new tab in a specific container requires either the Container icon in the toolbar or right-clicking a link to choose 'Open Link in Container,' since selecting which of potentially several configured containers to use requires a visual menu rather than a single predictable keystroke.
