thankyou!
Create a new profile and see if the issue persists.
is there a default settings for save session on exit?
i think the problem is browser.sessionstore
Yes, and if so, report a bug.
I just closed this and reopened it, so i have not this problem.
Something to try based on DeepSeek AI answer:
- Adjust Session Save Frequency Firefox saves sessions periodically. Increase the save frequency to capture recent changes:
- Type about:config in the address bar and accept the risk.
- Search for browser.sessionstore.interval.
- Change the value from 15000 (15 seconds) to 5000 (5 seconds).
- Ensure Session Restore is Enabled Verify these settings in about:config:
- browser.startup.page → Set to 3 (restores last session).
- browser.sessionstore.resume_from_crash → Set to true.
- browser.sessionstore.privacy_level → Set to 0 (stores all data; privacy-focused builds like LibreWolf may default to 2, which blocks session storage).
- Disable Conflicting Extensions Privacy/security add-ons (e.g., Cookie AutoDelete, uBlock Origin in hard mode) might block session storage. Test in Safe Mode:
- Go to Menu → Help → Restart with Add-ons Disabled.
- If sessions restore correctly, an extension is causing the issue.
- Check LibreWolf’s Privacy Settings LibreWolf tweaks Firefox for privacy, which can interfere with session restore:
- Go to Settings → Privacy & Security.
- Ensure Clear history when Firefox closes is unchecked.
- Under Permissions, ensure Allow websites to save cookies and site data is enabled.
browser.sessionstore.interval
thankyou ! i guess browser.sessionstore.interval is the problem here
is there a way to save session on exit without using plugins? (both normal close firefox and exit on crash?)
