min VS uc.css.js

FWIW, I found https://minbrowser.org/ and it uses very little CPU/Memory, but it uses DuckDuckGo and I prefer to use Google as my search engine... Also I do not think it supports installation of extensions?...

I tried Min, I found it both appealing and confusing at the same time. It has a minimalist design and it simply looks amazing, but it has a massive drawback: It is TOO MUCH minimalist, you get confused using it, also because it's very unintuitive to use at first. It's also one of the slowest I've ever seen (on Windows, idk about Mac), even without extensions (because yeah, even if it's Chromium-based, you can't download any extensions). I guess if dev's increase it's performances, add extension's compatibility, and make it less confusing, it would be a pretty good browser, but for now, it sleeps in my trashcan.

In the CachyOS installation itself you can select to install Firefox. I hope they leave that firefox fork behind and do something super-vitaminized with Min Browser. I think they could improve a lot making custom userscripts

Some browsers (such as Min Browser) don't have a status bar like Firefox or Chrome to preview the target (it can only be displayed in the context menu).

I know it is not but the browser reminded me https://minbrowser.org/

You can use Min, Fluid or any browser with full screen mode to have the same effect.

I love firefox, but the UI is to old, I like the Min Browser look

des navigateurs il y en a plein: min, puffin, otter, falkon, dot, privacy browser, orion, netsurf, maxthon (de mémoire il est douteux en termes de vie privée celui là), etc.

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
