My Firefox (under win 10 / Europe still gets OS updates)

Loading the page adds 250 to 300MB (300 according to Taskmanager, approx 
// 250 according to FF about:memory compare measurements)
Running "compiling world" adds another 50 to 100.
Repeated compiling does not further increase it (in task mgr)

And having Firefox idle seems to reduce memory usage (while the tab 
stays open) by most of it after a while.


Chrome  adds (task mgr) 100 MB to load the page and 100 to compile.
