I have a PC and my Internet explorer works fine but somehow Firefox is not working (not displaying pages) - what can I do to solve

Posted

I am not sure what happened, whether it was through a Firefox update or what but I have a PC running on Windows 7 and my Internet Explorer browser works just fine but my Firefox browser (which has been working previously), no longer works...gets a page cannot be displayed type error. I am wondering what advice is there to troubleshoot and figure out the cause. Since IE is working, it cannot be proxy or connection issues but it must be a specific problem with the browser (and yes I already did uninstall and reinstall as well and that didn't work either).

I like Firefox because it is faster and generally more efficient.

Additional System Details

This happened

Every time Firefox opened

This started when...

See Firefox can't load websites but other browsers can, a common cause is a firewall blocking access.

Hello,

I have very similar problem. Suddenly Firefox stopped work - It was working few days after ver. 4 update. I was looking everywhere for some solution but nothing worked. - uninstalled firewall - did not worked - added full exception for Firefox into the firewall - did not worked - Firefox reinstall - did not worked - Firefox complete reinstall (registry included) - did not worked - IPv6 diseabling - did not worked - diferent proxy options (no proxy, system proxy, autodetect proxy) - did not worked - new firefox profile - did not worked - complete coockies, history... deleted - did not worked - there is only one solution which partly works - I have used public proxy addresses for Firefox but the ping is (750ms), down/up (0.8MB/0.2MB originaly (10MB/2MB) and yes I have tried different proxy server from different countries from my included. - IE is working perfectly and without proxy - other companies browser - did not worked too - only IE is working - I have used three different malware, trojans, spyware, anti-virus programs and nothing

It seems to me as hopeless situation or very clever move from Microsoft, I am forced to use IE - at least this works

Any ideas, solutions?

System Windows 7, firewall Comodo Internet security

Thanks everyone for the help
