@goeblr : got an error with your vesion : TypeError: not all arguments converted during string formatting any thoughts ? thanks

Just a guess, but maybe the version of Firefox you're running is returning something other than a string for t['entries'][i]['title'] or t['entries'][i]['url']. Maybe a list or a tuple if there's something odd about the tab? I'd do a try/except, and print out type and size info for them on error.

The location for me was actually ~/snap/firefox/common/.mozilla/firefox/. You can find your profile location by the following the steps here: https://support.mozilla.org/en-US/kb/profiles-where-firefox-stores-user-data
