@JayfeatherThrag Save them as bookmaks and then open them all from imported bookmarks in GX.

@jgamel What version of Opera? Any difference if you change the theme?

@kamel-artist I sometimes just wonder how can one just... just mess up like that 😭
But still we all do, I just go back in History and recover my workspace 😂

@izyakantorovich Speed dials are avalable bur kept separate (in case speed dials from a personal device might not be appropriate or allowed on a work device). If you look into Bookmarks you'll see a section for "Other speed dials" which could be copied to yout current device's Speed dial folder.

I don't personally use sessions; I know the option exists but couldn't say for sure where to find tabs from other devices.

@turnipsandtea There isn't a setting for it.

Thank you very much !
I confirm that this method works 100%.
You can automatize the backup at regular intervals (for ex, each day) by using a free software such as "Backup Maker".

Bonjour,
Je confirme que la sauvegarde de "C:\Users\ordic\AppData\Roaming\Opera Software" fonctionne et suffit à restaurer complètement Opera en cas de crash.
C'est très pratique puisque ça restaure aussi tous les onglets, et de tous les groupes.
Vous pouvez automatiser cette sauvegarde avec la version gratuite de "Backup Maker": à faire !

@remzor Tabs Islands was released a while ago already.

@corpiecorpz Opera doesn't allow changing new tab page
