the undo closed tab has not been working since version 4 if i’m not mistaken. i read some suggestions that installing add-ons will solve the problem. I tried it, and yes it does solve the problem BUT unfortunately it only worked ONCE if i install/reinstall that add-on and restart cometbird. I mean, if i restart the cometbird again or restart computer, the Undo Closed Tabs button is still not functioning, but the add-on is still there in add-on manager…
is there any solution?
