If you wish to try userChrome.css

.tab-group-label { --tab-group-label-size: 26px !important; border-radius: 3px !important; }

Copy/paste the code into your notepad Save Type: All files userChrome.css

Create a chrome folder Move userChrome.css to your chrome folder

Go to your profile folder https://support.mozilla.org/en-US/kb/profiles-where-firefox-stores-user-data#w_how-do-i-find-my-profile

Move your chrome folder to your profile folder

Go to configuration editor https://support.mozilla.org/en-US/kb/about-config-editor-firefox Enter a search term toolkit.legacyUserProfileCustomizations.stylesheets Double-click on the preference, to set its value to true

And restart Firefox

That should work for the tab groups, but I mean moreso for the entire circular interface. I want my rectangles back, if that makes sense. Attached are some more examples of what I mean. I basically want it to look how it looked in 156 while still being able to keep new features and support.

You can add the code to the userChrome.css.
