On the below website, since firefox 4 was released it was working fine, but since firefox 4, it doesnt display certain text, please see below the two links provided of pictures, one displaying a picture from Microsoft IE, and Firefox version.

Firefox (It's not displaying certain text):

Now is this due to the HTML used or the browser?
Thanks

Answer 1

This is a little hard to diagnose from the pictures. I'm guessing that the box comes up blank at first and then is filled in from the server in real time after you make a selection from the drop-down control. Is that how it is supposed to work?
(Edit: I assumed the box was blank, but in case it is "white on white", you could try selecting that area, which would make it possible to see whether anything is there.)
Is there any part of the site that can be used without a login that demonstrates the same problem? (I went to the demo, but it's just a Flash movie...)
If not, you could check Firefox's Error Console (Tools menu). First click Clear, then reload the page that you want to use. There may be lots of warnings, but is anything marked with the "X" error symbol? Then click the link or button or drop-down that should populate the information. Check the Error Console for new errors. Although it's rare that you could fix such errors from your end, it might be possible, or you could report them to the site.
