It just started randomly, my web browser (FireFox) will not load pages. When i enter a link or click on a link, the web page will not load and the status at the bottom of the browser just says "Done" or the browser will show with an error saying "Connection Interrupted". I have to press Refresh or click the link about 10-20 times until it finally chooses to load. It is almost unbearable since web-pages take about 80% longer to load and the pages are incomplete without images and whatnot. I do not have a firewall but i am behind a router. The problem is, i don't know what i did. I did not change any setting, and it just happened overnight. I just reformatted my computer and i really don't want to do it again to fix this problem. any advice appreciated thanks.
PS: i have no add-ons on Firefox, I reinstalled removing profiles as well as trying new browsers but all come up with same errors. My torrent client is working fine also.
