Recently FF 50.1.0 has started to consume all resources on desktop running windows 10 to the point that typing is delayed for perhaps a minute.

Using safe mode and only one tab "about:performance" it uses 550 mb/6%. Open one other tab and it's 990mb/50%. Open ten tabs and it's about the same 50 to 60% and ~900 mb. When in "unsafe" mode, useing about:addons-Memory 2016 all of the add-ons are about 1 mb, so it's not the add on's.

I've alternated between different start up pages in case it was a particular page, but the function "about:performance" blames all pages, including "about:performance. I do not have the same problem in Chrome, with the same pages.

I love Firefox, but this just sucks
