[Bug 1474003] Re: Firefox 39 keeps crashing

[Chris Coulson]

One thing I'd like to understand is what causes the plugin process to
crash. Would somebody mind helping me with this?

What I'd need you to do is:

- Install debug symbols by running "sudo apt-get install firefox-dbg".
- Run Firefox and navigate to a page that embeds a plugin object (I assume that this is Flash that you're experiencing these crashes with?).
- Attach gdb to the plugin-container process running Flash by running "gdb -p <pid>" (where <pid> is the process ID for the relevant plugin-container). You might need to do this as root, depending on your configuration.
- Navigate away from all pages embedding plugins (best to close all but one tab and then navigate that to http://start.ubuntu.com/)
- Wait half a minute or so - until either plugin-container exits or crashes.
- If plugin-container crashes, please provide the stacktrace from gdb by typing "t a a bt f".
