This is why I always refuse to accept those “just edit the usercss to workaround your problem” - yeah and then It’s going to be a huge headache with the useless ui updates
I wish they have a “static theme” and normal theme that didn’t change with updates
In case anyone here is not aware, you can inspect the browser UI like you can inspect webpages, by using the Browser Toolbox: https://firefox-source-docs.mozilla.org/devtools-user/browser_toolbox/index.html
Unfamiliar with this, how do you get OPs toolbar using this toolbox?
Basically, you can write a CSS file to override the stylings that Firefox uses in its UI. So, you can’t edit the basic HTML-like structure, but yeah, you can do a lot with CSS.
Probably best resource to read up on this: https://www.userchrome.org/
There’s also a community here on Lemmy: !FirefoxCSS@fedia.ioIf you want precisely the layout that OP has, they’d have to post their CSS file…
I settled with the default Firefox UI. After a few years ob absolutely weird decisions the UI doesn’t really suck that much anymore. Except with the recent update the extremely rounded corners were introduced which are looking absolutely ugly.
The tabs look more like pills now.

Maybe it’s time to whip out the
userChrome.cssagain.sorry for rude language
It’s ok, Firefox updates also make me mad
This latest update messed up the experience on sideberry extension too. Now there’s a big chunky section whose only purpose is to display the name of the extension lol.
