I updated the example to use 2.4.1, and the workaround for Firefox's
cursor bug appears to be working fine (I see the flashing cursor) on FF
126.96.36.199 / WinXP and MacOS.
Here's a link to the workaround, running 2.4.1:
Do you see the text input cursor on the above link?
If so, can you post some additional details about how you tried to apply
the workaround, and we can look into it.
p.s. The overflow:auto you're applying to the "dlg" DIV by way of the
"caretfix" class is causing the scrollbar - and hiding the left and
right borders. It's designed to have overflow:visible. That's the reason
I chose to apply the workaround to the form (or some other element,
containing the text boxes).
