I have tried to locate the source of this annoying blocking of certain web sites pages while it wont block others. Example: when I go to Craigslist and go to "For Sale" or "Free" categories its's fine, but now for some stupid reason when I go to a personals category it's blocked out and hijacked to a blank page with a bunch of ''''''????????????????????????'''''' at the top of the page and nothing else and the status says "done" below. I've tried going to add ons and figure it out but I cleared all the pop-up blockers and I thought it helped, but it didn't. (And before you think what you are thinking the answer is "No - I don't live with a jealous gf or anyone else that has access to my computer...zilch!) It's frustrating when I click a toolbar location and it comes back blocked!
