Status: UNCONFIRMED

(Firefox :: Keyboard Navigation, defect)

Description

[Jacob]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:26.0) Gecko/20100101 Firefox/26.0 (Beta/Release)
Build ID: 20131205075310

Steps to reproduce:

I have no connection to Dirty Apron; I just experienced this issue on their site.

1. Go to https://www.google.com/#q=dirty+apron
2. Follow the result for www.dirtyapron.com
3. Follow any link within the site
4. Hit cmd + ←
5. Hit cmd + →


Actual results:

The image slider captures keypresses on left/right arrow keys, and Firefox does NOT navigate forward in history. cmd + ← also stops working


Expected results:

Firefox should have navigated forward/backward in history. Sites should not be able to capture, preventDefault(), or cancelBubble system command keys (ex ctrl on Windows or cmd on Mac).
