It happened with Aurora first.. My blinking solid line cursor would be used to scroll the page when I press the down button on my keyboard. Really got annoying, makes it hard to scroll etc. installed firefox in it's place, worked for a few weeks then it developed the same problem. I ignored it for a few months until a new problem popped up. The blinking sold line cursor won't scroll through my favorite website!! other then the tabs on the top and bottom of the website (contact us etc) IT won't scroll through the webpage... just jumps from the top to the bottom. I downloaded and installed firefox Beta hoping a different version would fix the problem like it did before. Nope, same thing... It's really drilling my nerves, any advice would help (can't use another browser because I am dependent on a firefox add-on known as greasemonkey and it's many beautiful userscripts that make some websites easier to use like fanfiction.net (which is the website I am having a problem in the most) )
