This seems like a good place to ask. There was a Firefox extension called (edit: not sure if it was Tab Mix Plus or something else) that was discontinued after Firefox 57. It was super productive and still haven't haven't found anything like it to replace it.
To be clear, I'm talking about grouping tabs but I'm not talking about the current Firefox feature called "Tab Groups". You had a row of tabs that showed the web pages open in the current group. And you had a second row of tabs that allowed you to switch between tab groups. You could close a tab group and close all the tabs within the group.
Has anybody found an alternative even if it's in a different browser? I dislike having multiple browser windows open.
Tree style tabs (Firefox) works in much the same way, assuming you have a parent tab for each group.
I routinely start a research task from one tab, say a search query, open all interesting results in sub tabs and close the parent tab including all children (ie the group) once I'm done (or I collapse the group when I intend to resume later).
Browsers are moving towards more restricted extensions and don't allow the unlimited UI edits that Firefox used to allow so it's unlikely that an extension would allow that exact functionality. Maybe one of the Chrome/Firefox forks could add it as a base feature.
It does bring back memories, I wrote what I think was the first extension that did that type of tab grouping. Was something like 12 years ago and even had the name "Tab Groups."
