I would have my Firefox browser open and I am looking at something and I decide to minimize it and go to my desktop to either open my computer or yahoo messenger, etc etc

Then I come back to the desktop and the Firefox browser is no longer minimized at the bottom of the desktop in a TAB.

So I open a NEW Firefox browser and lo and behold, a few minutes later when I go back to the desktop to look at something else; that disappearing Firefox browser TAB is showing up again which means I now have TWO Firefox browser opened at the same time!!

Anyone here using Firefox has experienced the same thing?
