@deke42 said in hello, is there a plugin that allows to restore all the windows that were opened when closing Opera ?:
I suspect the OP is suffering from the same problem as me
Yes. the OP is most likely asking how to restore open tabs/windows when the session gets lost/corrupted. When that's the case, you're pretty-much doomed unless you saved all opened tabs in a bookmarks or speed dial folder before the corruption happened. But, I believe others have said they worked around this by using a session manager extension that's not as brittle as Opera's session handling/storing/restoring. But, at the moment, I don't remember the particular sessions manager extension that users recommend.

when I logged on I'd be greeted not only by my previously open tabs, but also by the default front page (The TV screens). I thought it was a bit weird but not a problem and ignored it.
That's the new "Display start page first" option in settings at the URL opera://settings/onStartup. You can turn that off if you don't like it. The setting isn't supposed to affect Opera's remembered session and its opened tabs/windows, but I guess there's a possibility there's a bug in Opera with that. However, users have complained about Opera session corruption/loss way before that setting was introduced.
With that said though, on a stable system and stable Opera, with nothing interfering with Opera, if one properly closes Opera, opened tabs should always be restored just fine. In the event that Opera is unstable or not closed correctly or something interferes with Opera, all bets are off and Opera's session saving shouldn't be considered a backup mechanism for opened tabs.
