Firefox resizes to full screen when I type anywhere in Firefox

more options

I launch Firefox and start typing a URL or search string and the Firefox window instantly resizes to full screen. This happens only once after launching Firefox. I can 'restore down' and continue without the problem occurring again, unless I close Firefox and relaunch, and then window will resize to full screen when I start typing. Problem started about one month ago. Win 7 16-bit, FF 3.6.8. Thanks in advance!

This happened

Every time Firefox opened

== last Firefox update?
