Firefox on Android used to be a really good product--it supported basically every popular extension there was for desktop, then in 2018-2019 they appeared to start a new revamped project for some reason. I downloaded the beta for it--it was rough around the corners, it had a quite short whitelist of extensions, most of the functionalities were absent, but there were a few improvements here and there. And out of nowhere, a few weeks later they made it the default.
It's been way too long and the app still feels unfinished. It crashes way too much and I can't even move around the icons for the websites in the start page. They've enabled the list of extensions recently but it's a mess. I only use it since it's where I can have uBlock origin.
It feels that every couple of years they have a golden opportunity, but somehow they never seem to know what to do.
