Sure but we're acting as if a few people sticking to Firefox for the sake of it is going to save it, it's not. Not unless Mozilla fixes its underlying problems like the management and development roadmaps.

The fact that Firefox got backdrop-blur support in mid 2022 speaks volumes about Firefox's priorities.

I get the point you're trying to make, I use FOSS because I believe more people should be using it and if I don't, who would? But that doesn't work when it comes to Firefox. There are a lot of good free and open source browsers right now, no matter what engine they use.

If a chromium based FOSS browser gets popular enough, there are better chances of it surviving and breaking away from Google's monopoly at the same time. It does not matter what Google does with Chrome, as long as independent forks are able to exist within that same space and can get just as big.
