So no clues?

I thought I could automate this on exit but don't think its working right. So I change the option to "use custom settings for history" and tick all three options: Remember browsing and download history Remember search and form history Clear history when Firefox closes For "Clear history when Firefox closes" I ticked Browsing & download history and Temporary cached files and pages. https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2025-06-28-08-45-43-b10213.png The issue is the restore session option is missing and FF opens with all previous tabs gone. I am frankly not even sure what else is missing such as cookies, site data etc. Is this meant to work like so?

Unfortunately, it is not working the way you want because "session history" is part of "browsing history." When you clear "browsing history" at shutdown, that also clears the session history files that store your open (and recently closed) windows and tabs.

The difference from clearing history during your session manually is that 15 seconds later, Firefox starts writing session history to disk again, making it possible to restore your session.

If you want to clear browsing history automatically at shutdown, you could consider using an add-on session manager. I haven't tested these in years, so please check their reviews to see what issues they might have:

thanks for your response. Ok interesting. I was sure this is not working as expected.

So its working as expected? I haven't tested the history is being remembered or not but the previous tabs themselves not being opened on launch itself I was sure is conflicting of the settings I picked.

Would think either it should be greyed out(bring back tabs on open setting) or I be notified when I choose to wipe history with custom settings.

Sorry if I am not understanding but the options in the history on close itself are contradicting. See images please. The fact that I can make those settings itself is confusing as to what its meant to do on close.......

Update: Oh so the bottom option is only one for what it does on close...

The main boxes refer to saving history in real time. The Settings dialog is only for the feature to clear history when Firefox closes.

You need to stop clearing browsing history when Firefox closes if you want to be able to restore open tabs in your next session.

Ok thanks. I guess I should only do the cache since that's the biggest data hog.
