FF won't load pages, nearly at all. Some websites will partially load, but then will suddenly stop. In order to get the pages to fully load, I'll click Tools and open the Options menu, then I'll close the menu, resulting in the webpage loading up slightly more. I'll need to do that several times before FF will fully load a page. I can't even scroll at all through any of the webpages either when this happens. I'll hit Page Up or Page Down on my keyboard and nothing will happen. Also, I'll click other tabs on the browser and they won't move forward unless I do Tools > Options, and then close Options again. == This happened == Every time Firefox opened == Several days ago.
