Firefox 89-100 (2022) Tabs on top/bottom not working fixed again

9th May 2022

Firefox

Firefox - Codehaven

Works with Firefox version 100 – May 2022 onwards

Make the Browser Tabs appear at the Top

You use the tabs far much more than the URL bar, so it makes sense, and saves many miles on your mouse.
Put the tabs nearer, the action, and the URL bar further away, as it’s not as often used as the Favourites and the tabs to flip between websites.

Tabs on Top – URL on Bottom

Tabs on Bottom – URL on Top


1. Click Help > More Troubleshooting information
2. Open the folder button
3. Locate or create a folder here called ‘chrome’
4. Add a file called ‘userChrome.css’
5. Add the code below to that file and save.
To make the changes effective, we need one more thing:
6. Type about:config in the address bar. Accept any warnings to proceed.
In the search box on the about:config page, search for toolkit.legacyUserProfileCustomizations.stylesheets
and change to TRUE
7. Restart Firefox ….done Tabs are once again on the bottom.
