Suddenly 30 mins ago firefoxx did this, how do I re-enable them? I tried this, nope didn't work.

 

  1. Visit about:config and set the preferences:
  • extensions.legacy.enabled to true.

Fix is rolling out since an hour or something, should fix itself soon

I spent $2500 on building my PC and all i do with it is play no games atm & watch anime at 1080p(finally) watch YT and write essays...  nothing, it just sits there collecting dust...

Builds:

The Toaster Project! Northern Bee!

 

The original LAN PC build log! (Old, dead and replaced by The Toaster Project & 5.0)

"Here is some advice that might have gotten lost somewhere along the way in your life. 

 

#1. Treat others as you would like to be treated.

#2. It's best to keep your mouth shut; and appear to be stupid, rather than open it and remove all doubt.

#3. There is nothing "wrong" with being wrong. Learning from a mistake can be more valuable than not making one in the first place.

 

Follow these simple rules in life, and I promise you, things magically get easier. " - MageTank 31-10-2016

No, it wouldn't fix itself if you have studies disabled (like I do).

 

You need to type in the address bar:

     about:studies

Select "Update options"

Check "Allow Firefox to install and run studies"

Wait for "hotfix-update-xpi-signing-intermediate-bug-1548973" to install

Type in about:studies

Select "Update options"

Un-check "Allow Firefox to install and run studies"

The install took 10 minutes on one machine, other one is waiting for half an hour now...

 

PS: The old (now called legacy) extensions were a terrible design, security-wise and shouldn't be enabled, not that it would fix anything, since this is just FF certificate, used to sign the add-ons, expiring.
