System Details: Firefox 66.0.3 64bit Ubuntu 16.04.6 LTS (Xenial Xerus) Linux version 4.4.0-145-generic (buildd@lcy01-amd64-027) (gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.10) )

Opened Firefox one day, and soft-locked my system for several minutes. Killed it... repeated this process over a few days. Today finally opened it and just let it run to see what would happen. Ate all available ram. Then the swap. When it finally maxed both everything emptied out. System is now using less than a gig of ram and about half a gig of swap for everything.

Any idea what just happened and how I prevent it from happening again? I will also note - I have a lot of tabs.
