Firefox using over 1GB of RAM, multiple processes running and all this with only one tab open. Then it slows to a crawl, I have to close and restart FF. Rinse, repeat.
Fix memory leak and unneeded open processes. These are not features, they are defects.

Hi
Do you have many add-ons installed in Firefox?
What OS? What version of Firefox? If windows, can we get a screenshot of the task manager performance tab?
