The Bugbug bot thinks this bug should belong to the 'Firefox::Session Restore' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Hi Oana! 
Thanks for the assistance. 

- This issue did not happen when I switched to the 'default' profile (I was previously in 'default-release'). "Not happening" means: a) the non-pinned tabs were restored and b) the settings page had the "Open previous windows and tabs" checkbox checked.
- Couldn't install the nightly version as of yet (low available space and lack of time)
- 
- Support info is attached


Once again thank you for your time.

• This issue happened partially when in troubleshoot mode: a) the tabs were restored upon Firefox restart in Troubleshoot mode but b) the settings page showed the "Open previous windows and tabs" checkbox UNchecked.
• Support info is attached

Once again thank you for your time.

Could you please confirm if this issue is still reproducible on your end after updating your browser?

• This issue happened partially when in troubleshoot mode: a) the tabs were restored upon Firefox restart in Troubleshoot mode but b) the settings page showed the "Open previous windows and tabs" checkbox UNchecked.

So your support info shows browser.startup.page: 0, which would mean that "Open previous windows and tabs" is in fact disabled. When you're not in troubleshoot mode and this issue happens, can you confirm that "Open previous windows and tabs" is still enabled?

Hi Oana and Dão,
Yes, the issue is still reproducible with Firefox 116.0.3
And yes, when not in troubleshoot mode, the issue happens and the "Open previous windows and tabs" checkbox is still checked.
Thanks

Could you re-attach the information from about:support? This checkbox seems to disagree with the information from the about:support you attached 3 months ago. I wonder if it has been changed since. Also, do you have Sync set up to sync other devices?

Hi Sam,

Indeed I check the checkbox, close the settings page, open it again to make sure the box is checked, close Firefox and open it again and then the checkbox isn't checked (consistent with the about:support info). This non-sticky behaviour is the problem (or, more precisely, the fact that the change takes place before firing up Firefox, apparently). I'm pasting it below anyway.

As for other devices: yes, one Ubuntu 22.10/23.04 and one Android 13. At the time I first described the bug, I hadn't touched the Ubuntu machine in three months (it was shut down for more or less that time as well), and as of today the last time I used it was two weeks ago (and shut down ever since).

```
