Firefox is not a supported browser, you're not supposed to be using that at all.
Also, WebDirect 13 is two versions old now, v14 had a 25% speed boost and stability updates, 15 had more stability updates.
As for why it's happening, it's probably temp files interfering or the WPE needs to be restarted.
For the first one, just clear your browser's temporary files completely and refresh the page.
For the latter, you may need to contact your hosting company.
As a design preference, I usually suggest not using portals in WebDirect, with the preference being plain list and form views.
