Hi, Thank you for bringing that up! Could you please try creating a new [[Manage Firefox profiles|Firefox profile]] and see if the issue is reproducible there? In case you use the legacy Profile manager, remember to set your current profile as default again after creating a new one. If the issue reproduces in a new profile, I'd greatly appreciate it if you could [https://bugzilla.mozilla.org/enter_bug.cgi?product=Firefox&component=Untriaged report it on Bugzilla], Mozilla's bug tracker. That will let the developers take a look. If you don't feel comfortable enough with filing a bug, though, just let me know, and I'll do it for you.

Thanks! I'll give that a try, I'll try to run both profiles at once. One without extensions (the new one) and one with (my default profile).
