Hey everyone. I'm just migrating to floorp (first time maining firefox in 15 years) and I'm wondering if there's any good workspaces extensions. I think I've tried them all, but i've found nothing that let's me handle workspaces across multiple windows the way vivaldi does.

Basically what I want is workspaces the way vivaldi handles them. You can create a workspace and add tabs to it. you can select to open a workspace in a new window so when you close the window that workspace is saved and you can reopen it whenever you want.

What I've found with the workspace extensions I've tried so far is that when you open a new window, none of your workspaces are saved, so it's like a blank workspace. Floorp has workspaces but it only works for one window at a time.

Does anyone have suggestions how I could replicate vivaldi's workspaces functionaltiy without going back to that browser?
