Why did my add-on's stop working
I have seen the notice that talks about how from Firefox 57 and on only extensions that were built using WebExtensions APIs however when I opened Firefox today all of my extensions aren't working and I am very unsure why there are no extensions working. Any help is greatly appreciated!

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.

Sorry Robin, please ignore that message about legacy vs. WebExtensions.
A critical certificate expired (which obviously should not happen). 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 this option isn't ideal.
