Can I clear cookies upon closing LibreWolf and then have it reopen previous tabs upon startup? As I understand it, activating the "Delete cookies and site data when LibreWolf is closed" option also tr

i do believe that tabs cannot reopen unless browsing history is preserved.

if you enable Clear history when LibreWolf closes, but click Settings and uncheck Browsing & download history (everything else should be ok), then it should clear cookies but keep history (whats in CTRL+H menu). i also have 'Delete cookies and site data when LibreWolf is closed' enabled.

it is confusing how the options are layed out...

Now I understand. Thank you.

I use an extension to delete history after a week.

You can set it up to only clear cookies

Why is Session Restore not working? Session restore will not work unless you preserve your browsing history. However, LibreWolf deletes history on shutdown by default. If you want to use session restore, set your browser to not delete history, via settings or overrides.
