Text Cursor in Firefox
 

Why can I see the text cursor everywhere? I'm running firefox and this is bugging the crap out of me. I think it may have to do with a plugin I installed, but I'm not sure. Is there anyway to disable this?

I only complain because some times it makes it so I can't simply down arrow my way down a page, or even use the page down button without clicking somewhere else first.

I'll include a link to a picture in case you don't get what I mean by "text cursor".
