Infinitely reloading page - FF3 RC3

[mishgo]

Hi all,
On some pages, after using FF3, I find that it's constantly reloading the page. It will load the page completely, then blank the page and reload it (as if I'd hit refresh). Rinse and repeat ad nauseum.

It's driving me nuts - example pages are phpMyAdmin pages, and Commsec (an Australian web share trading site) watchlists (I know the commsec watchlist page normally has a 5 minute refresh on it, but this is a 0 second refresh!). I never had a problem with FF2, but have to load up IE to view these pages.

Any ideas what the cause/possible fix could be?

Do you have the Skype extension? (Tools > Add-ons)
You can start Firefox in -safe-mode to check if your problem is caused by an extension or theme (try the default theme).
