Pages don't load or load slowly in Firefox 20 and 21

Firefox isn't loading websites while other browsers are working perfectly. It often shows "Server not found" error and doesn't load sites 9 out of 10 times. It loads sometimes but very slowly and many elements are not displayed properly.

Things I tried to fix this: 1. Disabled DNS Prefetching 2. Disabled IPv6 3. Cleared Recent History (Everything) 4. Reset Firefox 5. Created a new profile

Any pointers?

hello, maybe your security software is blocking the new version of the browser. try to clear all rules for firefox.exe & plugin-container.exe and let the firewall detect the new version of the program again. Fix problems connecting to websites after updating Firefox

I pretty sure that my Antivirus is not blocking the browser. I also tried Waterfox and Cyberfox, both have the same problem.

Boot the computer in Windows Safe mode with network support (press F8 on the boot screen) as a test to see if that helps.

This problem has cropped up again in Firefox 24 for me. I am utterly confused. I have tried all things mention here: [Firefox can't load websites but other browsers can]

Does it have any effect if you boot the computer in Windows Safe mode with network support in case your security software is causing this problem?
