I too use only two extensions, uBlock Origin and HTTPS Everywhere and the hotfix pushed by Mozilla re-enabled them within half an hour of disabling. I do sympathise with those who apparently lost the settings of certain addons, notably Container based ones. Fortunately I always found the UX of Containers so clunky that I never bothered.
Sticking with Firefox as an open competition to the browser monopoly is critical now more than ever before.
