I don't get adverts on Facebook? Nor do I get game requests, pokes or any other annoying thing that intrudes upon my idle time.
I installed the Facebook Purity browser extension, and all of that went away.
I now browse FB with no trouble, no bugging, none of the "Eat this and never diet again!" adverts that look like some kind of tropical disease. I also get a lot of hand customizations that give *me* far more control of Facebook than they're really happy with, which is why they had to change their page from "Facebook Purity", to "Fluff Busting" Purity.
I have noticed that it also blocks Facebook's third-party cookie system, meaning I can't comment on LiveFyre, Discus and other commenting systems on other sites. Annoying, but probably just a configuration issue I haven't figured out yet.
