I used to have a very unpleasant viewing experience on various sites due to annoying ads, until my sister recently pointed me towards adblock plus. It's not perfect (very few ads still slip through), but it's pretty darn close. Good job.

В общем, работает хорошо, но периодически перестаёт блокировать рекламу на Youtube и прочих сайтах, а так же, сваливает страницы и/или полностью браузер.

I can effortlessly watch YouTube and navigate sites that otherwise give you billions of pop-ups; I can't live without this Firefox extension. The author(s) are to be commended, if I could donate I would.

It has been a wonderfull add-on. However, in the last couple of days, every time I open a Firefox window, it says that all the filters are reset... so I have to change the setting every time I open firefox.
