GNOME Bugzilla – Bug 752576
Huge memory usage as you scroll down through Google+ pages

Let's use https://plus.google.com/+ZeeshanAli/posts as a test case... Just loading that page, Epiphany eats ~270 MB of RAM for that WebKitWebProcess. Then if you start scrolling down, by the time you reach posts dated March 2015 the memory usage has ballooned to ~500 MB and more! Somehow, Firefox (according to about:memory) manages to keep the page at <100 MB at all times.
Quite likely a memory leak, or at least a serious inefficiency. Please report this on bugzilla.webkit.org. Thanks!
