firefox-revert-proton VS FirefoxCSS-Store

I have found [github](https://github.com/intrnl/firefox-revert-proton), that suits me, but it lacks square edges. Any idea how can I fix that?

So far the best one i have found is this one intrnl/firefox-revert-proton

That requires Mozilla to maintain two completely different UIs. The logistics to do that would not be worth it. If you want the old UI you can use https://github.com/intrnl/firefox-revert-proton

search for it on https://firefoxcss-store.github.io/ if you need assistance go to r/FirefoxCSS

yes, we can put "links of interest" on the web to collect all the communities, websites, or whatever related to firefox themes.

You can also remove that unnecessarily large sidebar header that Firefox insists on not letting users disable via normal means with userchrome mods. Some such setups can be seen at https://firefoxcss-store.github.io/.

firefox's ui is very customizable with css and i dont see why flatpak would change that. here are some examples https://firefoxcss-store.github.io/

I like to use this

If somehow this could be integrated with the css store down the line, I can see a lot more casual Firefox users finally trying out css customisations.

you can find others here https://firefoxcss-store.github.io/
