Border color gone in Firefox
In my html views I include table, where I control the border color as follows:
#inhalt {
border-collapse: collapse;
border: 1px solid red;
font: 12px arial;
}
This works fine in Chrome and until recently also in Firebox. But in the newest version of Firefox the setting only controls the outer border of tables. Is this a Zoho bug?
See attached picture.

Support has edit access to my app (bmpm).
