Tab Layout

Hello, since yesterday I have a different layout of the tabs in the Firefox browser for Windows. I would like to have the old layout again where the tabs with the dividing lines are shown. is that possible?

Hi , There's a Firefox theme on the addons site called Photon Colors, which I found helps a lot.

Go to and click on Install Theme.

The lacks of dividing lines turns out to be an issue for numerous users. I can give you a quick short-term workaround, but a more durable solution will require more work.

Temporary Fix

For testing purposes, there is a preference to switch the tab bar and address bar between new style and old style. This is not expected to continue in Firefox 90, but maybe you want to use it for now.

(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button accepting the risk.

(2) In the search box in the page, type or paste browser.proton.enabled and pause while the list is filtered

(3) Double-click the preference to switch between true (new style) and false (old style)

Longer Term Community Workaround

This involves setting up a userChrome.css file. I have a rules builder that will get more features throughout the month. By the time the above preference is removed, it should be mature. If you want to take a sneak peek now:

I don't like it either. The whole point of tabs is they show, a bit like dividers in a folder.
