After I close Firefox it opens a new little window on its own. Can it be fixed?

Whenever I close out my Firefox (1.5.0.1) window, within 2-3 seconds a new little Firefox window opens up in the upper left corner of my desktop. It's only about an inch long and the width of the title bar itself and it's not a real browser window. The only options for it are to minimize it or to close it. If you close it, it will open right back up in another 2-3 seconds. It's really not a problem, just an extreme annoyance. I have a screenshot if anyone needs to see it.

I've tried searching google and looking through Mozillazine's forum, but couldn't find anything. Mainly because I have no idea what to search for. Anybody have any ideas?

Thanks.

 

Mine does this to (same version), but it is merely to clear out private data (cache, cookies, passwords, history etc.) The setting are on tools, options, privacy, settings. Could it be that the window is so small that you can't see what it contains. Probably too simple a solution but maybe you can drag it to make it bigger and see if there is any data in it??

No, it's not the privacy setting window. This little window opens up no matter how many times I close it. I can't drag it to make it bigger or anything. All I can do is move it around the screen, minimize it or close it.

 

What extensions,do you have installed?

Firefox, can act weird pending on what type of extensions you have.

 

thefool, I have the following extensions installed.

Linkification 1.2.3 (not compatible with this version of FF, but I can't uninstall it)
DictionarySearch 1.5
Tweak Network 1.1
Forecastfox 0.8.5.3
Image Zoom 0.2.3
PDF Download 0.6
WellRounded 0.43
BBCode 0.4.1.3
OpenBook 0.6.0.2
QuickNote 1.3.4
MenuEditor 1.2
FLST 0.8.5
googlebar 0.9.15.08
Tabbrowser Preferences 1.2.8.8
Autofill 0.3
Gmail Manager 0.4.3.4
Cutemenus - Crystal SVG 0.9.9.71

None of these are recent installs. I had them all before and then I upgraded to the newest version of FF and had to update quite a few of them. Even after that, I didn't have any problems until this window thing just started all of a sudden.
