firefox-gnome-theme VS uc.css.js

if you use gnome, have you also tried firefox-gnome-theme?

Together with https://github.com/rafaelmardojai/firefox-gnome-theme it's all you will ever need

I recently installed Firefox-gnome-theme from Github. When I tried to uninstall it, it wont go back to original Firefox theme. I even tried to install Firefox again after uninstalling the one with Gnome theme and removing every folder with Mozilla or Firefox in its name.

I just checked this discussion here (https://github.com/rafaelmardojai/firefox-gnome-theme/discussions/447) and it seems this theme is not tested/might not work well on Windows :( sorry my comment was misleading, I didn't think this post was going to get this much traction.

oh. for firefox there's a good solution.

This is probably for you then, https://github.com/rafaelmardojai/firefox-gnome-theme

It's nice in theory to try to have a cohesive design, but as soon as you start downloading additional apps, thing will start being less and less coherent. Maybe you'll get Firefox to match the rest of the system (but that will require a separately maintained CSS for every ,theme like what Rafael Mardojai does for Firefox), but apps Chromium, OBS, Steam, Discord, Spotify? It's not realistic to expect every App to maintain a version that fits every DE there is. The only thing I would care about is that the apps come with a Light/Dark mode and follow the system preference.

If you haven't seen it already the GNOME Firefox theme is really nice for consistency https://github.com/rafaelmardojai/firefox-gnome-theme

probably this one

I'm using this script which enchances the all tabs menu functionality of FF.

Woah, this is nicely packaged. Even has "Releases"! Thank you! https://github.com/aminomancer/uc.css.js

Yes. It is possible, but you will have to set up a JavaScript loader. See this GitHub page for more info. https://github.com/aminomancer/uc.css.js

UI customization is fortunately still alive in the wake of XUL extensions.

A /r/firefoxcss mod has a wonderful collection of code snippets that they maintain, which you can browse here: https://mrotherguy.github.io/firefox-csshacks/ and they created a userChrome.js loader here: https://github.com/MrOtherGuy/fx-autoconfig

My favorite customization repository is https://github.com/aminomancer/uc.css.js - which really tests the limits of what is and isn't possible with userChrome.css and .js. My favorite feature is the implementation vertical tabs, without the use of extensions.

Some legacy extensions are maintained and can be found here: https://github.com/xiaoxiaoflood/firefox-scripts/tree/master... (although you will need to use xiaoxiaoflood's userChrome.js loader AFAIK).

Honorable mention goes to the Firefox CSS Store, which can be found here: https://trickypr.github.io/FirefoxCSS-Store.github.io/

Moving to WebExtensions was the logical choice for Firefox, technical/security reasons aside, as they are not alienating extension developers that target Chromium-based browsers.

Yes, they alienated their own extension developers. Yes, they could've handled the transition better, and worked harder towards supporting some of the many APIs/functionalities that extension developers needed (or still need) for their extensions to work in the WebExtensions ecosystem. I myself was quite mad for a very long time at how they handled the switch, but I think overall it's been a success - my own personal feelings aside.

Linux support is pretty good these days and it's just as customizable as Vivaldi. See this repo for an example: https://github.com/aminomancer/uc.css.js
