I use firefox, I mostly like it, but it still doesn't support chromium style tab groups (no, that one extension is not similar), and its webgpu implementation also doesn't work on most websites more than a year after Google made their version available by default
Tab groups are in the works but we haven't heard anything new about it since March.
Mozilla could definitely be putting their development time into the areas that the browser is actually behind in
Not sure if this is “that one extension”, but I use Simple Tab Groups for Workspaces-like functionality, similar to Edge and Vivaldi. I know, it isn't tab groups, but I use it similarly.
I'm using AdNauseam instead. So ad networks, what exactly are you collecting?
Click fraud is a big thing, with lots of counter measures, I don't see how they could go past them as they are saying themselves that they have a very naive approach. To me it's useless at best, but more probably counterproductive.
the number of forks says ff is next. the ad machine needs your money.
