Firfox 8 is sometimes very slow to load random websites and others it loads quickly, IE8 loads all websites ok. Have cleared cookies and cache and allowed ff as exception in Windows firewall.
I use FF 8.0 (x86en-US) as default browser, since update to 8.0 FF intermittently takes ages to load some websites, sometimes not loading the site at all. To rectify this I go back one page to the Google results or hyperlink and ask FF to load the webpage again. This usually solves the problem but not always. I have cleared cookies and cache and added FF to exceptions in windows firewall. The websites affected are not always the same and some that load quickly one day can take ages next time. IE8 loads all websites OK. Antivirus and malware scans all clear.
