To clarify, by 'not working' I meant none of the addons with signing issues are re-enabled after changing xpinstall.signatures.required. I might have wrongly assumed this would happen. However, I tried installing a new addon I had never installed before and that works, but reinstalling one that I had previously installed still doesn't, even after uninstalling it (uBlock Origin). My timezone is America/Los_Angeles. EDIT: Sorry, I'm dumb. I actually have two versions of FF installed and I chose the one that wasn't Nightly.
