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

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

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.

sorry for rude language

Not trying to laugh at your suffering, but your title reminded me of motherfucking website.

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.css again.

the new theme is hideous. thankfully easy to disable ...for now.
