Since a few weeks, I'm having occasional issues with FireDragon crashing with "Gah. Your tab just crashed". It mostly happens on YouTube.
I cleared all cache, cookies and history.
Rebooted FireDragon in Troubleshooting Mode to disable all themes & plugins.
Go to YouTube, click on Subscribe tab, and hover over some of the videos.
Gah. Your tab just crashed.
Some days it works, some days it doesn't.
It works fine in FireFox.
