Tweaking Adobe Flash Player

As you may have noticed, flash player uses /tmp/plugtmp* directories for storing some sort of temporary files and it doesn't delete them causing a lot of stale plugtmp directories in /tmp. If you want those directories to be removed when you exit your browser, just create an "adobe" directory in /etc and an "mms.cfg" file in it, which contains the following lines, and save it:

#/etc/adobe/mms.cfg
AssetCacheSize = 0
