I’ve been using the web clients of Proton Mail and Drive for a long time in Librewolf. Today it suddenly is stuck on the “Loading Proton Mail…” screen, getting no where. Still works in regular Firefox. Tried disabling both uBlock Origin and NoScript for the tab in case some settings there suddenly were changed, but did not help.
This is very frustrating.
EDIT: After a second reboot it now works again. Unsure why it took two reboots, I’m glad it works.
Maybe try it out on standard Firefox as a quick test? While annoying, this would help validate that the issue is with the librewolf changes to standard Firefox.
Also note that I also use both proton mail and drive from librewolf. Even today. If it’s a general issue with this setup, it hasn’t hit my machine (yet)
Yes, I’ve checked this, and it works in regular Firefox.
