Please implement Workspaces in the way that current Opera browsers have. It's an incredibly slick way to compartmentalize things, which is super helpful for neurodivergents like myself. I'm currently utilizing separate/different browsers to achieve similar.
Basically a vertical list of icons for each Workspace on the side (a button in the toolbar with a dropdown to select Workspaces would suffice), that instantly switch to all the Tabs open in a given Workspace and hides everything else. Pinned Tabs stay with each Workspace. Tab Groups can exist within a Workspace.
I've tried all the "similar" Firefox addons people suggested throughout the tubes, but as Prince said, "Nothing Compares 2 U".
E.g. I have:
I'd likely make even more use of them if they were in my preferred browser. (fanboi since Phoenix🔥🦅)
No idea how this would translate in mobile, not concerned with that for the time being. Desktop Firefox on Windows/Linux.
Also not concerned with being able to sync Workspaces across browsers -- I think we can already see open tabs in other browsers sync'd to our Firefox accounts, good enough for me.
