Firefox began it's e10s project from version 48 several years ago, which enables multi-process. However for me, it crashes ~30% pages on default settings, and 80% with my personal settings.
It's true on all 5 of my computers, running different CPU (Intel/AMD), different OS (Windows/Linux/MacOSX), and even applies to several computers of my friends that I never accessed before.
The bug is haunting all version from 48 and up, including ESR. However, mobile versions are not affected because e10s are not exist on them.
All mess could be solved by disabling e10s in about:config, until ver 68. Now from version 68, e10s is hard coded as enabled, and they eventually killed Firefox for me.
I even tried a bug report, but fix never come.
I was suprised that I cannot find anyone mention it on the Internet, seriously, is it just me?
