Recently every time I open GOTD with Firefox (which is every day ;-) ) It would hang for a long period of time trying to load certain web sites. I finally figured out it was the PayPal toolbar (or plug in or whatever they call it). Disabling it makes everything right again. Downloaded the latest, no difference. Tried asking PayPal to exclude GOTD, but no difference. Works OK with IE.
Just thought that might help someone.
