uc.css.js VS blurredfox

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

I like it. Looks like Firefox proton with mica or like this theme https://github.com/manilarome/blurredfox

I want to get something like this. I tried blurredfox but didn't succeed, my bar is opaque. I'm using archlinux with KDE Plasma. I've read somewhere that it's not possible anymore, is it really so?

blurredfox

I am trying to make firefox transparent (like blurredfox), but i cant figure out how. None of the pre-built themes or CSS i find work, for example

I have already tried this setup. But I cannot achieve it.

I know I'm able to have transparent window elements since I've already tried out blurredfox, which (AFAIK) just makes the window elements transparent without using backdrop-filter and just relies on the system compositor (KWin Compositor + OpenGL 3.1 backend) to blur the background of the application. Editing the Firefox source isn't completely out of my scope of possibilities, but it's definitely not one of the ones I'm too exited about, but if i do get it working I'd be happy to at the very least share the fork and maybe even put it up on the AUR. But I'll definitely ask about on a few of the Mozilla matrix channels and see if there's any easy way to get it to work, and hopefully it'll end up being an obscure flag in about:config!

- The owner of the theme notes this (Transparency is broken on Windows 10 (has graphical glitches like flickering). The solid color scheme may work.).
