I have a fairly customized masterpage and while the modal dialog boxes seem fine in Chrome and IE, they aren't rendering wide enough in firefox causing them to need to be horizontally scrolled.
I've figured out that it's not my stylesheet because when I deactivate it the problem still remains. When I try going back to v4.master it also works fine, so I'm mostly positive it's my masterpage.
I've tried going through and removing various customizations but nothing seems to resolve the issue. I'm thinking it may be related to the ribbon which I have detached from the top of the page.
I'm hoping if someone knows how the width of the modal window is calculated I might be able to track down the bug.
I wish I could just set the modal windows to use a different masterpage all together or have more easily accessible css. Maybe Sharepoint 2012? :)
