After about a day or two of leaving Firefox on (This is due to me saving tabs), Firefox negates me from refreshing, going to a website, opening a link, middle-mouse buttoning a line to open in a new tab. It just won't connect, it's like it's running in offline mode. This sucks because The only way i personally figured out how to solve this problem is by restarting my computer. I wanted to know if there is a fix that can prevent this from going into this sort of "Offline mode," in which it prevents me from connecting to the internet. As i right this, about 15 min(s) prior, Firefox did the same thing causing for me to restart my computer. ~Thanks for any help received P.s. I've forgotten to mention that I have checked the " Work Offline-mode" button to see if it was on. It's not, nor has it ever been"
