On certain sites(example: http://www.lockergnome.com/hardware/2011/09/21/five-interesting-usb-hubs/) certain words are in blue and have 2 lines under them; when I hover my mouse over them an ad pops up. Is there a way of stopping this(although it will go away after the mouse pointer is moved; or you click the "X" on the ad)? It is very annoying.
You can look at Adblock Plus.
You need to subscribe to a Filter list (e.g. the EasyList).
