Not too long ago I would give Adblock 4 or 5 stars, but not any more. It opens it's just installed tab EVERY time browser is opened. Have to reset the settings EVERY time browser is opened. Have unchecked "Allow acceptable ads" but what do I get - ads - dancing ads, talking ads, singing ads - most times before the actual content of the page is loaded. The wifi connection is very slow and every ad makes it take that much longer for my browser to load pages. Tried but received no support or help from the developers or their forum.
