I reset the Windows OS on my PC. When I reinstalled Firefox and synced it, the extensions automatically returned but their icons were missing from the address bar. Worse they only work if I click the extension drop-down and specifically the extension. They used to be aware of the website and automatically do their thing. E.g. the NordPass symbol previously appeared next to passwords and I could click to have the password automatically filled in. Now I have to select the NordPass extension and copy the items one by one into the form. Ditto for Grammerly And still worse the setting was synced to my laptop.
