link location bar extension: this cannot be replaced with a webextension as mozilla refused to add the necessary API

websocket monitor extension: this is being built into the dev tools, after 2 years and counting

tab groups / panorama: every single extension that tries to replace this is terribly broken, because the provided extension APIs don't really support this use case or are super racey

like the link location bar extension it's impossible to write an extension to replicate the old refresh/stop/go button in the url bar. You can have 3 buttons, but that's stupid.

All that and mac (nightly & dev-edition) users only recently got back to the level of performance from pre 57 Firefox due to work described here: https://bugzilla.mozilla.org/show_bug.cgi?id=1429522#c26 (ongoing).

And before I get crucified: there aren't any better browsers, so I'll be sticking with Firefox, but it sure isn't anywhere near as useful as it used to be.

Giving a list of my needs is pointless. Also, I never said that Firefox was incorrect. I said that it no longer meets my needs.

Mozilla has made a business decision to address a user demographic that I am not a part of. I don't have enough information to be able to say if that decision was correct or not. All it means is that I no longer use Firefox.
