Well done. I don't know Mac's and called for help.

Thanks for looking into this. So it appears to be a bug in Firefox? If so, is there anything I can do to get around this issue or just wait for an updated version?

Please wait for help.

I hate to be a pain, but is anyone able to help out on this please? I've been waiting awhile and it's affecting our web developers in a huge way. They like the developer tools in FF and also need to test their sites in FF for compatibility.

Thanks..
