I like these new #firefox tab groups. Very useful for grouping default sets of sites you use at different times of the day.
@stsquad you have never used extensions which add tab handling improvements?
I wonder will Firefox ever get to the point where Tree Style Tabs extension is.
@hrw I use a few extensions but mostly for ad-blocking and privacy (#ublock, #privacybadger). I've found extensions that mess with the UI tended to cause issues at somepoint with my fairly aggressive browser upgrade schedule. I do use #refinedgithub to gloss over some of the UI failures of #github itself.
