To say that the 3.0 update sucks is far too kind. This is a travesty. Blaming WebExtensions is easy, but the developer has had ages to come up with something better than this - how did we end up with this feature-less, control-less, information-deprived, hideous, buggy piece of garbage? Amongst other problems listed here en masse, the options don't even stick!

Obviously nobody should upgrade to this version and if you did, then you should go to the "all versions" section and downgrade right away. Then disable auto-plugin-updating and stick with Firefox 56.0.2 for the foreseeable future.

What's really sad is that Adblock Plus is why people use Firefox. With this ugly train wreck of a release, Firefox is going to die. The worst thing is that the developer couldn't see forward into the future and move over to a better browser project like Pale Moon. If he'd done that, Firefox would have went to its grave and Pale Moon would have become the next great Mozilla-esque project. Bad decisions will leave both browsers as inconsequential remnants from the past.

All good things....
