Why add-ons won't start with Firefox? Every time I need to manually disable and enable extensions Privacy Badger, uBlockOrigin (Privacy out of the box extensions) for it to be working, that is, they don't work upon start up. I have deleted the .mozilla folder in my Linux machine to reset firefox and it starts with add-ons only one time; when starting a second time, add-ons don't appear in the toolbar yet they are "enabled" but not working. As previously stated, I need to enable them manually.

The Add-ons Manager is loaded just that you probably have the "Get Add-ons" panel selected and ging the loading icon. Just look to the left and click on the Extensions and if you go back to "Get Add-ons" panel later it should load.

The "Get Add-ons" panel can sometimes load slowly in displaying stuff from, especially on first start probably due to both with people looking for extension./theme updates with the recent releases

It’s possible that there is a problem with the file(s) that store the extensions registry.

Delete all extensions* files and compatibility.ini in the Firefox profile folder to reset the extensions registry.

New files will be created when required.

After, restart Firefox.
