The history of Firefox UI is important because my project compensates for the shortcomings of this Proton UI and inherits the strengths of the existing Firefox UIs.
It’s also one of the ways to prevent divisions in the community, given that there have been forks every time the UI changes big.
A detailed timeline of the changes to the user interface of Firefox.
I happened to notice the displeasing (IMHO) proton theme just got pushed into Firefox ESR today, which is used by Linux distros.
Is this article’s timing purely coincidental or were you actually looking for a way to revert the UI changes?
Mozilla isn’t doing users any favors by removing the option from about:config, ugh.
Edit: I did install the UI changes using the manual method. Running a remote shell script is such a bad practice and shouldn’t be encouraged, it should be a plugin IMHO.
I don’t like the provided menubar icons at all, but the style does look better than mozilla’s changes.
