I’ve recently upgraded to Firefox 3 and have noticed a huge issue which is making me consider switching browsers (something I don’t really want to do).  When you click anywhere in the browser and go to drag, rather than selecting text or dragging the image (as you’d expect), the entire browser window moves.  This means I’m also unable to do simple things such as using the scroll bars!

I’m running Firefox 3 on Mac OS-X, and have never encountered an issue like this prior to the upgrade.  If anyone has any suggestions as to how to resolve this I’d be very grateful!
