Whenever my phone accidentally opens fandom with Chrome rather than Firefox mobile (with uBO), I wonder how the hell anybody browses the internet on their phone without an ad blocker...
It gets a lot better with an ad blocker and other annoyance-blockers. The deeper question is whether or not you think it’s worth it. I think many people visit Fandom pages only briefly from a SERP and then take off, like Wikipedia but specific to a game. If that’s the way you use Fandom then it’s probably not worth it.
What makes it worth it is if there’s a page specific to a game you like and you spend a good amount of time there reading stuff. That’s a long tail thing though.
Most of the time I don't notice it because I use Firefox w/ uB0 on all platforms. But recently I've been playing some games on Steam and trying to use Steam's browser overlay to cache some guides. Its browser seems to be a chrome fork and does not support any kind of adblocker, unfortunately, and so I've been exposed to just how bad Fandom wikis are without one.
