I think Mozilla has completely missed the point on how tabgroups are and why they are not something that can be replaced by bookmarks...<p>&quot;Removing the Tab Groups feature will make it easier for us to improve Firefox&quot;. Yes, how, what? What was the problem? What is the new thing that is so incompatible with tab groups that this has to go away from the code?<p>I found the feature recently and thought, oh, how nice, and since then I have tabs grouped by topics. For some topics (like research), I need many tabs open, but when I&#x27;m not working on them they are just nicely hidden in their group. And I can go back to the browsing state I was at a later moment.<p>At least they offer alternatives and a clear migration path. That is good even if the explanation sucks.
