That's undeniable. Thx to everyone. For me: eod.

Yes, you can, als long as the browser is open. What is the use of placing tabs in different spaces? When using the browser, I'm focused on one topic. So why should I separate weather tabs from politics tabs if I do not open them at the same time? It would be much more useful to place bookmarks in different spaces to make for a clear arrangement.

@leocg Yeah, but maybe I misunderstand tabs. Please describe what you do. Can I leave "open" a website in my workspace?

@leocg Yes, but why should I group tabs?

Thanks for two replies. If there are no different profiles, what is the use of different work spaces?

Windows 10. Moist recent Opera. How can I make different work spaces? At the moment, bookmarks are identical in my two spaces. If I delete a bookmark in one space, it is also deleted in the other. How comes?
