Front-End Developers:

It took me a while to get this going, so I figured I would share it in case anybody else comes across the same issue. On http://mercuryracing.com/techcorners/ when you click on “Join our email list”, in the div overlay that comes up, the blinking cursor bar failed to appear in input text fields in Firefox.

The Firefox bug report is here: https://bugzilla.mozilla.org/show_bug.cgi?id=167801

It is fixed with the code below, thanks to comments #50 and #51 on bug report page:
#emailListPopupContainer {
position: fixed;
position:expression(”absolute”);
overflow-x: visible;
overflow-y: visible;
…
}
