This forces me to re-start Firefox every 1/2 hour based on my hardware constraints (320MB of RAM)

There is nothing here to suggest a real problem except misunderstandings about memory management. In the future try reading http://plugindoc.mozdev.org/faqs/memusage.html and http://developer.mozilla.org/en/docs/Bug_writing_guidelines and http://dbaron.org/log/2006-01#e20060110a before filing such bugs.
