Speaking of slow firefox startup, I have the following issue:

When I begin typing in the navigation bar, the very first time I do it, the keyboard is slow to respond.

For instance, if I boot up the computer, and the first thing I do is open Firefox, then I type "empegbbs.com", after I press the first "e" there is a long pause before the rest of the letters appear.

It appears to be trying to scan through my browser history for populating the automatic drop-down list that appears when I begin typing. As soon as that list is loaded and appears, then firefox starts responding normally again.

Does anyone else get this, and is there a way to optimize this feature (perhaps an about:config entry) that makes the drop-down list into a non-blocking operation?
