I had no issue with Firefox 66.0.3 (64bit) and its extensions today:
- convert2mp3.net
- Cookie AutoDelete
- Disconnect
- EPUBReader
- Firefox Lightbeam
- Flagfox
- KeePassXC-Browser
- Open Tabs next to current
- Privacy Badger
- Startpage.com
- Tab Deque
- The Camelizer
- uBlock Origin
- Undo Close Tab Button
Running Ubuntu 18.04.2 LTS (need openJDK 8 and openJFX 8, therefor no update to 19.04):
- wake up from hibernation at about 07:00 AM (GMT), all extensions were working
- read the information here: https://bugzilla.mozilla.org/show_bug.cgi?id=1548973 after reading this thread
- restarted due to new Linux Kernel 5.0.12 installation at about 12:00 PM (GMT), all extensions were working
Did I miss something? Not that I really miss the issues reported here
Please do not understand me wrong: I'm sure there were a lot of users affected by the issue but presumably not all. Don't panic, the issue will be solved soon / is already solved. No need to switch browsers in a hassle
