Hey there, yes we have found (but still unsure why) Firefox 29/30 is crashing when using the CMS.

Investigated a bit and appears that 31 beta solves the problem suggest grabbing that or getting your clients to install until the official 31 stable comes out.

If anyone finds out the reason behind the crashes please post as we would be keen to know :)

Just wanted to add my 2 pennies as I have the same problem here with 29 and 30 and same explanation as Intodevel on how to replicate.

Personally, I downgraded to v28 and disabled auto updates.

You can do this by visiting and installing the correct version for your OS.

To disabled auto updates (essential if you don't want Firefox to revert back to v30 after it's restarted) click the orange Firefox button > Options > Advanced (cog icon) > Updates (tab) > Then select "Check for updates, but let me chose whether to install them"

EDIT: Also, be sure to disabled "Use a background service to install updates"

Hope that helps until v31 stable is released.

For me, the about:config solution mentioned has fixed the issue in Firefox 29.
