Cannot add Contact Email after 5.2.0f patch (Firefox Only)

[vdhooge]

After Installing the 5.2.0f patch half of our users running Firefox 3.0.11 lost the ability to add an email for an existing contact or a new contact. The email textbox is simply not there. These same users on the same machines can, however add contact emails using Internet Explorer version 7 or 8. I tried updating to Firefox 3.5 and even updating to the latest version of Java, but still no cigar. Has anyone else experienced this Issue, or know of a fix?

Additional Information:
PowerProspecting v 5.2.0f installed
Related Data Module v 5.2f installed

Try to clear your ff cache (under tools - clear recent history or private data in 3.0)
