Arch Linux

Description:
When Firefox is first launched, it will not accept keyboard input, but mouse input works. If focus is given to another window and Firefox is refocused, keyboard input is accepted.

If I work in another window and return to Firefox, it appears to be focused but doesn't accept keyboard input.

This behavior does not appear when Firefox is reverted to v 16.0.2

Additional info:
* firefox-17.0-1-x86_64.pkg.tar.xz
* fluxbox-1.3.2-1-x86_64.pkg.tar.xz
* xorg-server-1.13.0-4-x86_64.pkg.tar.xz
* linux-3.6.7-1-x86_64.pkg.tar.xz

Althoug I am using "MouseFocus" in fluxbox, the fact that I can click on the Firefox window and still not be able to enter text suggest it is not a focus model problem.

I reverted to 16.0.2 and the problem disappeared, which suggests it is not related to plugins or other add-ons (except for the possibility that Firefox 17 handles them differently).

I've attempted Googling this issue and only came up with old reports against earlier versions.

I will follow up with a test of 17.0 with add-ons disabled. Are there any other tests I can run?

Steps to reproduce:
1) Launch firefox
2) Attempt to type a URL or enter search terms. There will be no cursor and Firefox will appear to be frozen
3) Focus another window, then return focus to firefox
4) Text entry is now possible
