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

For me, it was enough to delete the "xulstore.json" file. After that, everything worked as before.

Hello,

I am experiencing an issue similar to what is described in this bug (Bug 1964260) with the sidebar's "Bookmarks" setting not being saved after closing Firefox. I would like to share additional details that may help with the investigation.

Environment:

• Firefox version: 138.0.1
• Operating System: Windows 10 19045.5737

Steps to Reproduce:

1. Enable the "Bookmarks" sidebar by going to View > Sidebar > Bookmarks (ensure the checkbox is ticked).
2. Go to Settings > Privacy & Security > History > "Clear history when Firefox closes" and enable it.
3. In the "Clear history" settings, check the box for "Browsing & Download History."
4. Fully close Firefox (not just restart, ensure the process is terminated).
5. Restart Firefox and check the "Bookmarks" sidebar setting under View > Sidebar.

Expected Behavior:
The "Bookmarks" sidebar checkbox should remain enabled after restarting Firefox.

Actual Behavior:
The "Bookmarks" sidebar checkbox is unchecked after restarting Firefox, and the sidebar is not displayed.

Additional Observations:

• This issue only occurs when the "Browsing & Download History" option is checked in the "Clear history when Firefox closes" settings.
• If I uncheck "Browsing & Download History" in the clear history settings, the "Bookmarks" sidebar setting is correctly saved, and the checkbox remains enabled after restarting Firefox.
• The issue does not occur when restarting Firefox without fully closing it (e.g., using the "Restart" option).
• I have not tested with a new profile or by resetting xulstore.json yet, but I can provide further details if needed.

Workaround:
Disabling the "Browsing & Download History" option in the "Clear history when Firefox closes" settings prevents the issue from occurring.

I believe this issue is related to Bug 1964260, as it involves the same sidebar setting not being saved. The interaction with the "Clear history" setting may provide a clue about the root cause, possibly related to how Firefox handles places.sqlite or xulstore.json during history clearing.

Thank you for your efforts!

Best regards,
