When opening Firefox, the first few tabs work fine. But once i start to open too many, they begin to just time out until i restart my PC. I have looked on my router and it is saying the session limit for my PC's IP is being exceeded. Hence, once ive opened a few tabs on Firefox, no browser or internet connection can work as the session limit has been reached. I have my session limit to 1500, Firefox should not be using 1500 sessions. Any ideas? Thanks
