[horde] Firefox bug or what?

[Erling Preben Hansen]

Hey

Is it just me or is there a bug in Firefox 35.0

This happens in Horde groupware 5.2.4 default theme

When i choose Calendar week view in Firefox 35
The line between Tuesday and Wednesday is missing.
and every 6. line down the page is missing too.

When viewing same page in Google Crome there is nothing wrong.

It seems Firefox has trouble displaying the border-spacing correct
