Plugin Container for Firefox taking up to 1.5GB RAM without any plugins installed

I haven't installed a single plugin but the Plugin Container for Firefox is taking huge amount of system resources, up to 1.5GB RAM and 40% CPU usage.

I am using 3rd gen i5 with 256GB SSD and 8GB RAM and Firefox version v49.0.1

Even while typing this, it is taking about 500MB RAM.

hi adeelnm, in the new multi-process architecture that is getting rolled out in recent firefox releases, other web content might run in the plugin-container.exe process as well: https://blog.mozilla.org/futurereleases/2016/08/02/whats-next-for-multi-process-firefox/
