I'm unable to install any addons or themes because Firefox thinks I don't have an internet connection.
So I have just reinstalled Windows 10 because I got a new SSD and Firefox is one of the first things I've installed. There is no antivirus or firewall software installed except for Defender that came with Windows 10.
Right after installing Firefox I login to my Firefox account and it should start downloading my addons, except it doesn't (except for just 1 strangely). I go to the official Firefox addon page and try to install something and it tells me "Download failed. Check your internet connection". My internet connection is fine as I am posting this and I was able to download Firefox.
I can't find a solution to this particular problem. Any help is appreciated.

Hi EnigmaNL, sorry, terrible timing!
A critical Add-on-related certificate expired (which obviously should not happen). As a result, all verifications for that certificate are failing, preventing many extensions from being used, updated, or installed.
The Add-ons team is working on a fix for this. Official updates are expected to be posted here:
Currently, the only workaround is to set your system clock back (for example, if your date is May 3, set to May 2; if your date is May 4, set to May 3). You might have to reinstall extensions after that, or maybe Firefox will detect the difference at your next shut down/restart. Changing the date may have other consequences, so I understand this option isn't ideal.

Installing addons from third-party sites also does not work.
AH HA, another person that sees the big picture!

Thank you jscher2000! I just set the date back to May 1 and installed all my addons and then set the date back today. Everything works!
Mozilla has rolled-out a fix for this. The fix will be automatically applied in the background within the next few hours, you don’t need to take active steps.
In order to be able to provide this fix on short notice, they are using the Studies system. You can check if you have studies enabled
- Go to [=] > Options > Privacy & Security.
- Make sure Allow Firefox to install and run studies is check marked.
I you had it disabled, you can disable studies again after your add-ons have been re-enabled.
They are working on a general fix that doesn't need to rely on this and will keep you updated.
