Yeah, just browse to the addon page (e.g. https://addons.mozilla.org/en-US/firefox/addon/ublock-origin...) and click "add to Firefox", it works as usual. Not on iOS, though, since Apple doesn't allow real third-party browsers.

iOS / Safari / Content Blockers are not as full-featured as Android / Mobile Firefox / uBlock Origin, but I'm quite content with https://1blocker.com/ , it provides several lists (with a less stringent limit than the crippled webRequest API discussed here) of rules to pick from, and the possibility to create your own rules through a Safari extension.

Apple does allow real third-party ad blockers though.

Depending on your opinion of content blockers, not on iOS.

The content blocking API it allows on iOS is significantly less restrictive than Chrome’s proposal
