Having just 1 tab open -- my gmail -- firefox is taking nearly 1GB of memory. Opening an empty tab pushes to memory used over 1GB. Also there are 12 listed tabs in the Task Manager.

I already took multiple steps. Cleared cache and cookies. Put in troubleshoot mode and refreshed. Minimized memory usage via about:memory.

Please help.
