How to clear Acroread defunct process in Linux?

Acrobat Reader plugin works fine for first document, but if I close the pdf window and wait ~20 seconds, the Acroread process goes defunct and further attempts to read pdf docs do not display (blank screen). Have tried disabling all other plugins and many extensions. Killing nspluginwrapper manually allows proper pdf reading (for one more doc). This has been going on for a number of Firefox releases.

ps info: 11976 ? Sl 0:00 \_ /usr/lib/firefox-7.0.1/plugin-container /usr/lib/nspluginwrapper/plugins/npwrapper.nppdf.so -greomni /usr/lib/firefox-7.0.1/omni.jar 11767 true plugin 11989 ? S 0:01 \_ /usr/lib/nspluginwrapper/i386/linux/npviewer.bin --plugin /opt/Adobe/Reader9/Browser/intellinux/nppdf.so --connection /org/wrapper/NSPlugins/nppdf.so/11976-2 12000 ? Z 0:01 \_ [acroread] <defunct>

The question: Is there something that can be done to fix the problem in Firefox or is it purely an Adobe problem?

I remember this has been a problem since Ubuntu 9.10 (maybe). It seems that Firefox 3.0+ has a non-robust interface with Adobe PDF reader. Chrome doesn't have this problem on Linux. So I guess the problem is in the plug-inn wrapper. I think Firefox team need to fix this problem ASAP.
