I opened around 12 tabs with different pages on jalopnik.com, reload all tabs, let browser opened for an hour, reload the tabs again, but no crash. I do see memory usage increase, but no hangs or crash.

Firefox 45.0.2 
Build ID: 20160407164938

I'm getting an OOM crash when loading 16 jalopnik.com pages in different tabs.

I'm also seeing an unresponsive Firefox if I open 11 jalopnik.com tabs but I'm not getting the crash mentioned in the Description. I'm attaching the memory report I took when the CPU started to increase.

Shawn seems to be gone. And the crash sig is dead nothing in version 60 or newer.

https://jalopnik.com loaded in several tabs does not crash for me
