830779 - The navigation bar of my site doesn't expand with the new version of Firefox

Status: RESOLVED INVALID

(Tech Evangelism Graveyard :: English US, defect)

Description

Attachment: Unknown.jpeg

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:18.0) Gecko/20100101 Firefox/18.0
Build ID: 20130104151948

Steps to reproduce:

When I hold the mouse over a menu item on http://www.betathetapi.org the child menu items don't expand properly. This problem is specific to Firefox v 18.0. The site renders perfectly on all other browsers and older versions of Firefox.


Actual results:

All of the child menu items seem to stack on top of each other. 


Expected results:

The parent menu should have created a drop down menu with all of the child menu items contained within it.

I can't reproduce this with Firefox 18 on Windows7 and OSX10.8

Can you please try it in the Firefox safemode ?

Is this report about OSX or Windows8 ?

Works for me with 2013-01-15-03-09-36-mozilla-central-firefox-21.0a1.en-US.linux-x86_64.

Are you using a single monitor?

I tried to access the site in safe mode, but no dice. The issue was replicated on OS X, Windows 7 and Windows 8. I am using a single monitor.

The site uses: MooTools={version:"1.2.5"
This version is known to be broken in Firefox18, please read bug 789036
