Firefox never finishes loading certain websites
This article explains what to do when specific websites (not all) start to load, but never finish (i.e. the tab displays a spinning wheel and "Connecting..." for several minutes).
- If Firefox cannot load websites but displays an error message at the end, see Firefox can't load websites but other browsers can and Websites don't load - troubleshoot and fix error messages.
- If none of the web browsers on your computer can load websites, see Firefox and other browsers can't load websites.
If none of the below solutions work, try the methods described in the Troubleshoot and diagnose Firefox problems article to see if they will address your problem.
Search for malware
A variant of the Vundo trojan is known to cause Firefox to have problems loading certain high-traffic sites, including Google, Yahoo, MySpace, Facebook, and more. Not all variants of the Vundo trojan can be detected or removed by malware scanners.
However, you should scan your computer for infections first. For detailed instructions, see Troubleshoot Firefox issues caused by malware.
