There's a bug in Firefox going around that disables all of your add-ons. I got hit and I have version 66.03 64-bit. Not sure if other versions are affected.
Haven't found a (good) workaround yet.
Here's a reddit thread on the matter:
This one has Mozilla's statement on the screw-up
I wonder how many are affected. I'm using 66.03 64 bit and my addons are working.
I'm back to normal now. Looks like they rolled out an automatic fix this morning.
I got no notifications when my add-ons mysteriously vanished (thank you for posting about this!). Didn't get the automatic fix until I'd updated to the latest version (I was one iteration behind). and even then I still had to manually re-enable several add-ons and the theme. Poorly handled, Mozilla.
