Prior to the website rpmfind.net, installing software was to put it mildly, a chore. Due to package dependency, you’d start the compile, and it would fail due to missing libraries. You’d then go out and find those libraries, only to have them fail on compile…due to missing libraries…it would go on like until you finally were able to compile the original package - at this point though you compiled it out of sheer spite for the universe that put you in that position.

I rate the experience a solid 5/7

The last time I looked at containers I think it was an add-on, but I don’t think (and please correct me if I’m wrong), it filtered or made active the current viewable tabs.

In Opera there’s an icon list on the left and depending on which one is selected those are the only tabs displayed, and/or made active. I’ll take another look at FF containers.

Someone mentioned ‘about:profiles’ above, I think that may be closer to what I’m looking for, maybe that combined with containers can reduce my foot print to just Firefox, thanks for the suggestion

That’s unfortunate, I was hoping for a ‘workspaces’ like feature as in Opera. I run FF and Opera simultaneaously to segregate my tabs. It would be really nice if we could get something like that extended to profiles, so I could just run FF
