Contacts only load in safe mode in FF on Mac

Contacts only load in safe mode in FF on Mac

Hi, using the latest Firefox 4.0.1 on OSX 10.6.7 and the contacts don't load in the right pane, it hangs on "Loading..." (see screenshot). It only works if page is loaded in "safe mode". Tried disabling Adblock Plus and NoScript but no go. On Windows it works fine with the same browser and Adblock Plus and NoScript active. Works with Safari on Mac too but I prefer Firefox. Anyone seeing the same?
