Sometimes Firefox stops to send/receive all tcp packets, so there is no any site available to open. There is no even request to server, when i try to open any site. During this stuck firefox.exe takes 25% of cpu usage (one of 4 cores), perfmon says - One of process threads wait for network Input/Output. It looks like socket is blocked on some operation for some reason. Only firefox restart can help in this case. So what can be a problem ?

hi, does it make any difference when you manually clear the cache folder while firefox is closed?

press windows-key+R and open: "%localappdata%\Mozilla\Firefox\" an explorer window should pop-up, in there delete the folder named "Profiles" and run firefox again.

What kind of internet connection do you use?

How is the router connected (USB or fixed network card)?

Boot the computer in Windows Safe mode with network support to see if that has effect in case security software is causing problems.

Router connected via ethernet cable into the motherboard embeded LAN. Other net applications (Steam client for example) are work good, even when firefox is stuck. I just need to restart it and it will works. But i dont know why firefox blocking its own sockets sometimes. My cache is empty by default (disabled).
