Firefox tabs not saved on restart
The subject line say it all. I'm running version 80.0.1 (64-bit) on Ubuntu.
- Preferences / Startup / Restore Previous Session is ticked.
- Deleting all sessionstore files (as per https://support.mozilla.org/en-US/questions/1185765) doesn't fix it.
- There is no Restore Previous Session item available anywhere (https://support.mozilla.org/en-US/questions/1261571)
This appears to have only happened since the last upgrade. I regularly work with 20-30 tabs open at a time so it's very annoying, and if it wasn't for the Session History Scrounger for Firefox (https://www.jeffersonscher.com/ffu/scrounger.html) I'd be totally screwed. The latest version is also cripplingly slow at times, frequently consuming 100% of CPU as shown by the 'top' command.
