Memory consumption of main proccess

[RandallFlagg]

OS: Windows 8.1
Firefox: Developer Edition 49a02

Hi,

I am using the e10s version of firefox(49a02) and when this addon is enabled my memory consumption(Commit size in task manager) shows me 3GB of memory being used when no tabs are open.

When I disable the addon it drops to 1.2GB.

What I did OR steps to reproduce:

1. Use firefox and wait for main process to consume a lot of memory
2. Close all of them.
3. Perform "minimize memory usage" in the about:memory page.
4. Notice that memory footprint didn't change.
5. Disabled the addon in about:addons page
6. Notice that in a few seconds(~5) the memory dropped from 3GB to 1.2GB.

Regards

P.S.

Great addon!
