I hate that Firefox 57 has completely gutted what addon developers are allowed to do. Reading a few homepages of my favorite addons is a sad state of affairs. Couple developers gave up and left to do other things due to firefox deciding to close the doors and use this quantum e10 crap as excuse to close doors to developers making addons that we could use to do whatever we wished.

we had a rating system so we self policed the bad addons as it was. But Mozilla is destroying firefox

now im reading in future they want to monetize addons and charge money for addons using the firefox web store to buy extensions and buy themes.

wtf they think they are apple now?
The old UI worked. It was intuitive. I hate being forced to a seperate tab to control anything. Stop opening tabs!!!! give me a hover based UI.
