[Bug 126012] Re: Firefox memory usage increases to point of no response

[k c davis]

I'm seeing Firefox occupying increasing memory every time I go to a new
site, as if it was caching it in RAM, but not freeing it when I leave
and close the window.  This is new behavior,  -maybe- only after
upgrading to 9.04, or latest Firefox upgrade.  It'll go to the point of
filling my 4 GB RAM, then apparently start thrashing the swap file, with
Firefox essentially frozen.   Only way to get RAM back is to close
Firefox, watch cleanup run and RAM return to normal ( < 500 MB used, no
swap. )

It's "only" a performance annoyance, but as a 40+ year programmer I'm
inclined to view it as a probable indication of a serious problem in
Firefox or it's interface with memory management.
