Title:
  Firefox 7.0.1 memory leak

Status in “firefox” package in Ubuntu:
  New

Bug description:
  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.
