Table selection (operations) do not work properly in FF

[Kentico_MartinH]

Create a simple table in FCKEditor in Firefox. Select all cells. Click on the "Justify to center" toolbar button. The table gets corrupted and its code is like:

<table width="200" cellspacing="1" cellpadding="1" border="1">
    <tbody>
        <tr>
            <div style="text-align: center;">&nbsp;</div>
            <td style="text-align: center;">xxx</td>
            <div style="text-align: center;">&nbsp;</div>
            <td>xxx</td>
        </tr>
        <tr>
            <td>xxx</td>
            <td>xxx</td>
        </tr>
        <tr>
            <td>xxx</td>
            <td>xxx</td>
        </tr>
    </tbody>
</table>

Which is obviously not valid. It works correctly in IE and I can confirm that it also works correctly in FCKEditor version 2.4.3 in Firefox.

Is there any workaround or easy way how to rollback the changes to the previous version code?
