Unable to Edit Records in View Mode

when attempting to edit a record in View mode the pop up window will not display properly.

The pop up window will distort half way down with the inability to edit any fields past a certain point. The submit button will not appear and any fields past the half way point overlap and distort graphically as well.

this is only happening on mac versions of firefox browser. I have replicated this error on multiple computers.

i have submitted this bug previously but have not received any comment. I have also posted it separately on the zoho forums page with no reply. There I posted the image of the issue as well.
