Firefox crashes whenever I try to change an updateable input dropdown box after I have already set it, and it has only been doing this since the update.

Since the latest update, whenever I change the input of a dropdown box that is updateable, as in you can change one dropdown box to change the available options of another dropdown box depending on the first's setting, whenever I try to change it to something else even in the same list firefox immediately crashes.

Such a change usually makes JavaScript send an AJAX request to the server to request an updated page.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

  • Do not click the Reset button on the Safe mode start window or otherwise make changes.

I'm having the same issue. I have a application that loads a combo using ajax.

While Firefox doesn't "crash", it becomes unresponsive.
The tricky part, is it does work in other computers (with same version of firefox), and even in the same machine with an older version (I tried FF 9, portable).
If I load the page with out ajax, it loads ok, and I can display the options in the combobox.
