Can't save Files

Just out of the blue, I can't save ant downloaded files. I've tried to save to different locations including 2 different external drives but nothing saves. Kinda wish I hadn't gone paperless with my bank now. Sorry if this wasn't the place to post.

seems there was something wrong with Firefox. I just uninstalled, deleted all files associated with firefox and reinstalled. Poof now it works. I did import all firefox's bookmarks to explorer first so I could get them back.
