I'm using Moodle 1.9 and just upgraded to FF4. Now all my table borders have disappeared. They still appear as expected in IE8 and Chrome, as well as the editor.
Typical FF4 table code added using the table properties function
<table border="2" width="100%" rules="none" frame="void" style="border-color: rgb(0, 0, 255); border-width: 2px; background-image: none; float: none; text-align: left; vertical-align: top; border-style: solid;"><tbody>
It seems to be this part, rules="none" frame="void", that is causing the problem. If I remove that, it appears okay. That code seems to be added by the table properties button, and I'm not sure why it adds it. If I remove it will it break in some other browser (or future browser)?
Since I have many, many tables is there any easier way to fix this? This could be very tedious. Any insight is appreciated.
