Now since we know it is not all browsers with this issue as i asked the thread starter to try other browsers since it was never mentioned they did try others. This then should eliminate the fact of it being the touchpad or mouse issue unless due to an add-on from a touchpad software in Firefox. Simrick mentioned a good point i would of then mentioned once i knew it was only Firefox doing this.
Although i still feel may be something with these certain sites unless all sites do this.
