not only is this a seemingly random site that needs you to use an account to access part of the information, all you need to do is not look at a random site that pulls stats out of their arse like you say, they dont explain where the data comes from, they dont explain anything.

I dont need to pull random ass data from that sketch site, this small amount of legwork is far more than necessary nor what you deserve for being a dick about it: (lets not forget you just say "elsewhere" without showing us, well, anything)

firefox addon site users:

ublock origin: 6.713.504 adblocker ultimate: 2.286.976 adguard adblocker: 991.481 block site: 518.605 adblock plus: 4.236.338 ghostery: 1.104.375 adblock for firefox: 1.166.799

everything else is too small and inconsequential to mention, same with github, thats a total of 17.018.078, firefox usercount FROM firefox, about 188 million

https://data.firefox.com/dashboard/user-activity

since webstore doesnt use proper numbers we can only assume but:

adblock best adblocker: 10million+ adblock plus: 10million+ adaway: 2million+ ublock origin: 10million+

thats again, only super roughly but 32 million users compared to chromes rough 3.3 BILLION users

both of these may nto be exactly 0.01 % sure, but we are all inconsequential and mean nothing compared to the total count of uers, who barely know what a browser is, let alone what an adblocker is.
