Pretty interesting analysis from TechAltar about Mozilla usage and revenue trends, which aren’t as dire as they’re often made out to be, but how the search placement deal with Google is indeed endangered, which may be pushing them to their recent embrace of adtech as a new revenue source
I’ve had this issue on several Pixel devices - I most recently had this exact issue on my Pixel 6 Pro, but I think recent-ish Firefox updates resolved some of the issues.
In my case, Firefox would lockup, but I could easily switch to another app without an issue. I would have to kill the Firefox app to get it responsive again.
