htmlArea RTE: Merging table cells using context menu doesn't work in Firefox
Like the title says if you want to merge table cells using context menu in Firefox it will not work as expected.

A patch containing a workaround for this issue is attached.
Gecko based browsers merge cells in a specific (and apparently broken) way, and the workaround makes merging cells work the same way in all browser, i.e. using two popup dialogs for getting the number of rows and columns to merge.
