MinimalA Firefox theme for Windows 11

A quieter Firefox.

Minimal turns Firefox into a single slim row on a flat graphite frame, so the page is the only thing that shines.

The installer isn't code-signed, so Windows will say "Windows protected your PC". Click More info, then Run anyway.

This download is for Windows PCs. Open this page on a Windows 11 computer to install it.

Firefox with the Minimal theme open on a Wikipedia article: tabs and the address bar share one slim graphite row above the page, with no menu bar or extra icons

One slim row

The address bar sits in the tab row, with the menu at the far right. No menu bar, extension icons, account button or divider lines. Hold Alt for the menu.

One accent

A single soft 1px hairline marks the current tab. Menus and Firefox's Settings pages get the same flat treatment.

Out of the way

New tabs open blank. Bookmarks slide up from the bottom edge; pinned sites appear in the empty address bar.

The Minimal installer window, headed 'A quieter Firefox', with an Install button

Safe to try, easy to undo.

Backs up your Firefox setup first and keeps your settings.
If Firefox is open, it closes for a moment and reopens with your tabs.
Run it again any time, for example after a Firefox update.
To remove: Settings › Apps › Installed apps › Minimal theme for Firefox › Uninstall. Firefox goes back exactly as it was.
