i use adblock plus but find AdwCleaner extremely useful too AdwCleaner is a free removal tool for : Adware (ads softwares) PUP/LPI (Potentially Undesirable Program) Toolbars Hijacker (Hijack of the browser's homepage)
Another Adguard fan here. I grabbed a "good for 180 days" version from a promotional link that sid_16 provided. Supposedly, this promotional version had to be installed and activated within 30 days of the promotion. I saved a copy to my cloud server and I'm glad I did. Someone didn't do a very good job of testing the "must be activated within the 30 day promotional window" feature, because I can (and have on many computers) install anytime I want and get a 180 day period from it.
Same here,not available on mozilla addons site.Available only on adguard website. Edit: btw using Bluhell firewall (firefox). Howcome Adguard selling their windows product for $20 but giving free extensions for chrome,FF,safari and opera.
