Brett is finding that this is somehow connected to AdBlock+ in his FF. Both cade and I have it as well, and it's working here. I'm not sure what his issue is. FWIW, I'm on FF 23.0.1 with Adblock Plus 2.3.2 on 10.6.8.
Yes - I disabled ad block, restarted, and the problem went away. Re-enabled, restarted, and problem re-appeared
I'm on FF 24 w/ adblock 2.3.2 on osx 10.8.4 Also, this problem doesn't appear for me in chrome.
I'm on FF 25.0a2 (2013-09-07) using ABP 2.3.2 on OSX 10.8.4 Cannot reproduce the bug with or without the add-on disabled.
Brett, can you give this another shot with the add-on enabled?
Not experiencing this any longer. Must have been gremlins!
