Windows 7: Screen remnants Firefox 9.0.1

I notice in Firefox 9.0.1 on both a laptop and a desktop that closing Firefox leaves remnant stuff (see photo) above the taskbar. The remnants appear after opening and then closing the bookmarks list.

Pressing WindowsKey-D to redraw the desktop clears it. Nevertheless is this a Windows 7 issue or a Firefox issue? Anyone else having this problem? How is this solved?

BTW, my graphics card is up to date.

Thanks.

Uhm.... did you try another version of FF ?

No issues here with Firefox 9.0.1. Hopefully it will settle down & behave.

Didn't happen with an older version.

uninstall. restart. re install. check if its back to normal.

Hmmm. I tried to uninstall it, but I couldn't. I'm clicking on "uninstall" in Control Panel's "Programs and Features," and nothing happens. I then tried to run helper.exe, and that also didn't work (nothing happens).

Also, I see in the programs listing that version 3.6.8 is listed, but not 9.0.1, which I recently installed and am currently running. Did 9.0.1 install over 3.6.8? Shouldn't both be listed? And since I'm running 9.0.1, where the heck is it?

weird
download and install ccleaner CCleaner - Optimization and Cleaning - Free Download go to tools>uninstall and check if FF is listed there. if it is, uninstall it and post back.

Same listing in CCleaner ( I use it often!). Version 3.6.8 is listed even though I'm using 9.0.1.

did you download and install firefox? or did it auto-update its self? which version did you have installed before 9.01?

Well, I downloaded "Firefox Setup 9.0.1.exe" and re-installed it. It's listed correctly now in "Programs and Features," version 3.6.8 is gone, and I then successfully uninstalled 9.0.1 and reinstalled it.

However, the screen remnants are still there!

Any suggestions?

BTW, thanks, koolkat77, for sticking with me on this.
