firefox.exe process remains after closing Firefox

more options

I closed Firefox 5 over 45 minutes ago. At the time it closed, I had around 60 tabs open. The Firefox window closed, but now, over 30 minutes later, firefox.exe is still consuming 624 MB of memory. For the record, currently Windows Task Manager shows firefox.exe consuming 00 CPU, 639,772 K Mem Usage and a Peak Mem Usage of 771,296 K.

I'm seen this behavior at other times and, on those occasions, the firefox.exe process did eventually terminiate and release that memory. Why does firefox.exe take so long to terminate? Is this a bug or just a result of the way I use Firefox? I do tend to have a lot of tabs, 60 to 75, open at any given time. I'm guessing that's more tabs than the typical user.

I should go on to add that I have already seen the Firefox Hangs |Hang at exit document and none of these look like the obvious issue. I'm running Java Version 1.6.0_26, so current there. I'm not running any of the listed Internet security software. The only extensions I'm running are Java Console 6.0.26, ReloadEvery 5.0.0 and Xmarks 4.0.1, so not a lot of extensions.

As I mentioned before you replied, I had already looked at that document and nothing jumped out as being the culprit. Perhaps it is a Java applet, but I am on the latest version.
