This could be one of many problems, but one may be your firewall. Make sure you always have it on, because, remember, Trojans and such can cause problems with internet browsers and slowing of computers. If you must, uninstall your current anti-virus software and replace it with something that may be more secure. Trust me, nothing is the matter with Firefox. I'm using it right now, and I'm perfectly fine. My personal anti-virus software preference would be AVG free 8.5, which includes anti-virus, anti-spyware, e-mail scanner, ID protection (optional), license, link scanner, resident shield, and an update manager. And, there is always Malwarebytes' Anti-Malware, which is a great scanner and is highly preferred. It's guaranteed to do you and your computer some good. I have both, and trust me, together, they work greatly. Just always make sure to update them/scan for updates on a regular basis.
Or, this could be something with one of your ports. Always run scans, at least once a day or once every other day to make sure there aren't any Trojans or other infectious items coming in through an open port.
Just remember to keep your eyes open for anything weird/any infections you see in any files or you see come up in your results after scanning. Trojans and other infections are one of the main causes for strange computer behavior and this may be your problem. If you have any other questions, you can surely ask me. I may be able to help.
And so the lion fell in love with the lamb.
