Firefox 16 causes my menus to display incorrectly on my websites. Menus built with AllWebMenus software.
Dropdown menus (called from mouseovers) are shifted to the left in FireFox16 only. They are no longer aligned with the call box and not under the cursor. Firefox 15, Microsoft IE, and Google chrome all work correctly. Everything works except Firefox 16. This web page has been stable for several years (http://callawayfamily.org/)
Re: Firefox 16 causes my menus to display incorrectly on my websites. Menus built with AllWebMenus software.
It is working in Firefox 17 (beta) and later as well, so it seems that some code landed only in Firefox 16 that is causing the menus to get shifted that got fixed in later versions.
There is probably not much that you can do about this.
A good place to ask advice about web development is at the MozillaZine "Web Development/Standards Evangelism" forum.
