Off topic but I got the weirdest ads on this site. Has to be off putting to people attempting to read it on their phone in public. Had to close it before getting past the first paragraph.

Firefox mobile has extensions. I didn't get any ads because of ublock origin. No idea how people browse the web without adblockers. Not only because they are an assault on your attention, which is an important resource, but also because of the scams and security implications of ads.
