No one's forcing you to install or run Chrome on your non-ChromeOS desktop, for instance, so we surely must do it under our own free will.
Using a #/%& stupid Android tablet, a Windows pc and a Linux laptop and absolutely nothing prevents me from installing and using Firefox on any of them. *)
It's my deliberately choice not to and no matter what Mozilla say or how much they wriggle or moan, there's no chance I'll ever use Firefox.
Sorry. But have spent too much time digging old archives and do not like, what I've seen. Plus that stupid bookmark handling....
There are other reasons besides Google, Apple, Microsoft etc that Firefox have such a small user base...
*) using #%&# stupid Chrome on stupid android, Vivaldi on both laptop and pc, btw.
