It doesn't work on iOS. All browsers in iOS are Safari with a different frontend. Apple doesn't allow it to be any different.
But many browsers on iOS support ad blockers. Most like Brave and Vivaldi have it built in. Others like Orion and Edge have added support for extensions. Firefox is one of the only that does not have any support for an ad blocker.
