Give it another go. Mozilla's own extension called multi account containers is pretty good and it has more features than just grouping tabs together.

And there's also the panorama view extension, which looks really nice and I've seen people use it extensively.

Does it allow "saving" tab groups and having them sync with what you've actually put in them? Last I checked this was still an experimental feature in Chrome (it might be auto-available now), but it's a killer feature for me (it auto-syncs with whatever you add to or remove to the tab group also).

Mozilla providing the same would be required for me to make the switch altogether (though I happily use it for some things already)

Yep, the extension support syncing your groups across devices. You'll need a Mozilla account for this.

I'm not sure this is the case for panorama view.

Just in case you're open to something new: Tree Style Tabs is my goto extension to managing tabs on firefox

You manage your tabs vertically in a sidebar, organized as a tree. Every new tab is opened as a leaf from the tab that you came from, grouping your tabs by branches following your navigation on the web. This make managing groups of tabs by topics really natural.

Addressing grandparent's comment regarding lack of tab grouping, I'd like to share a custom stylesheet for TST that somewhat tries to tackle this:

Tree style tabs is not new. It predates containers and might even predate chrome

What is the security concern of Firefox over chromium?

Not the browsers themselves, but the extensions that provide tab group functionality - they often have the `Access your data for all web sites` permission.

Maybe I trust the developer right now, but one day they may sell their plugin to someone else. Obviously its the same story for uBlock Origin, but I prefer to restrict the number of extensions with these permissions, and its a shame to need an extension for what is provided by all the other major brwosers.

I don’t think those permission mean that they can collect the data and send it home. I think it means more something like „ accessing all code of website to block scripts“.

If the would send data home I would be a bit irritated. Could someone please clarify this ?

Because I know some extensions do exactly this . There was a talk from the ccc about this. But is this a Firefox specific problem ?

Thanks for responding anyway

Its FF specific as in, in chromium you do not need to install them as its a native feature

Try Tree Style Tabs. It's different but works very well. Edge even stole vertical tabs, I wish Chrome also did.

Maybe Vivaldi would be a good fit for you?

You need Vivaldi if you like tab groups.

If you like tab groups, try Arc.

I like how every single person who recommends Arc never bothers to mention that it's Mac-only.
