Firefox 7.0.1 memory leak

[Leonardo Morelli]

I think there might be a memory leak in Firefox 7.0.1.
Memory usage with 5 tabs opened: 697916(mem) 37376(shared mem)
I even reached 1GB of memory usage a few days ago.
Firefox 6 used to have this memory leak problem too in my machine, and I didn't experience an improvement after upgrading to 7.
I tried creating a new profile and deleting the current one but the problem persists.

We are sorry that we do not always have the capacity to review all reported bugs in a timely manner. This bug was reported some time ago and there have been many changes in Ubuntu and Firefox since that time.

Ubuntu 11.04 (natty) reached end-of-life on October 28, 2012.

We'd like to close this bug report due to its age and long period of inactivity so please let us know if you still see a problem which is related to the one that was reported in a currently supported version of Ubuntu.

If we do not hear from you this bug report will expire in approximately 60 days time.

Thank you for helping make Ubuntu better.
