(Facebook triggers this bug semi-regularly.)
It is unacceptable that a single malfunctioning webpage should be able to wreck the browser so heavily. Chrome does not do this; and even Firefox (50.0.2), while a rogue JS thread does
choke its renderer, it does not lock up the core browser and UI; consequently, its "Stop Script" dialog works quickly and as intended.
- CPU: i7-920
- Pale Moon 27.0.2 (x64)
- OS: Mint 18 XFCE
(Will provide any further configuration details requested.)
