Hi antonugr, it wasn't intentional. A critical certificate expired, causing most extensions not to verify. A patch is being pushed out through the Study system.

Over the next few hours, your Firefox should automatically get that update. However, please check your settings on the Options/Preferences page as follows:

  • Windows: "3-bar" menu button (or Tools menu) > Options
  • Mac: "3-bar" menu button (or Firefox menu) > Preferences
  • Linux: "3-bar" menu button (or Edit menu) > Preferences
  • Any system: type or paste about:preferences into the address bar and press Enter/Return to load it

In the search box at the top of the page, type stud and Firefox should filter to the "Firefox Data Collection and Use" section. Here, make sure you have a check in the box for "Allow Firefox to install and run studies". (First screenshot attached.) If you prefer to turn it back off after the patch comes through, that's fine.

So far, I have received two studies related to this, which you can see if you click the View Firefox studies link next to the above preference (or paste about:studies into the address bar and press Enter to load it). (Second screenshot attached.)

If you receive the patches and your extensions remain disabled, check whether they now show an Enable button.
