User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:44.0) Gecko/20100101 Firefox/44.0 Build ID: 20151011030229 Steps to reproduce: Open around 4 tabs or more on latest Firefox Nightly. Actual results: Very high usage of processor by process "Plugin Container for Nightly", around 70-95% and more than 1 GB of RAM, apart from main browser process. Browser hangs, especially while switching between tabs. Expected results: Plugin Container should not use such many resources.
I would like to say that I have quite powerful laptop.
