I'm operating in Firefox 3.0.5
on a new MacBook White w/ Leopard.

When I open the new mini-window to change the Properties of a Fast Dial link/box, the "OK" button is permanently grayed out. I can change anything I want WITHIN that box (title, URL, logo, etc.) But NONE of it is permanent, because I can't click the "OK" button. So I just have to shrug and close the mini-window in defeat.

What could cause this pretty critical bug?? Why can't I click OK?

Other Add-ons in Firefox are:
Ubiquity
WebMynd
Download Statusbar
Ctrl+Tab
Cooliris
AdBlock Plus

They're all updated to newest versions.

Thanks in advance for your help! :)
