Complete, authoritative list of Firefox extensions officially recommended by Mozilla.

Some quite informative discussion on Firefox subreddit when I discovered and posted the above list there a few months ago.

The Recommended Extensions program description: https://support.mozilla.org/en-US/kb/recommended-extensions-...
I seem to remember TamperMonkey being on there but not ViolentMonkey, which I didn't agree with. However, I see neither of them on there. Both are available but not recommended. I wonder what is going on with that.
Probably just resources. Mozilla has to vet each update to give them the "recommended" badge and so they probably focus on the most popular extensions
They should have vetted ViolentMonkey instead of TamperMonkey the last time around.
