so every website that has some sort of sign in like "username" and "password" (facebook, webassign, yahoo, aol, tumblr, twitter, etc.) doesn't work for me. i'll type in my username and password but when i press enter, the bottom left bar will say "Connected to facebook.com..." or whatever site i'm on and just stay there. so, i exit out of firefox, but when i try to go on firefox again, i'll get a pop-up saying that a firefox process is already on or something, and the only way for me to get back on firefox is if i go to "processs" on the windows taskbar and disable the process itself. any thoughts to what the problem is? i tried figuring out if it's a virus or something like that but i'm lost on the whole computer software/processes stuff. thanks.
