It used to be engineered especially for power users, respecting their interests and needs. Not so much these days. Reverting my about:config settings every time I update, for instance, just conditions me to dodge updates.

One example of this is removing the ability to open local files on mobile. Or forcing browser restarts on the desktop in the middle of browsing.

It specifically sucks now in almost every aspect it used to rule 10 years ago.

Starting from performance, dev tools and finishing with annoying and shitty ui “enhancements”.
