When using the typo3 extension “rtehtmlarea” there is a compatability issue with Firefox 2.0.0.3. The issue is explored on the typo3 bugtracker here and here. Toward the bottom of the list of comments you’ll find the solution. I’ve tried it, and it works. Here’s the boiled down solution.

in this file:
sysext/rtehtmlarea/htmlarea/htmlarea.js in line 85
change this:

HTMLArea.is_wamcom = (HTMLArea.agt.indexOf("wamcom") != -1) || (HTMLArea.is_gecko && (HTMLArea.agt.indexOf("1.3") != -1));

to this:

HTMLArea.is_wamcom = (HTMLArea.agt.indexOf("wamcom") != -1) || (HTMLArea.is_gecko && HTMLArea.agt.indexOf("1.3") != -1 && HTMLArea.agt.indexOf(".1.3") == -1);

Then disable the compressed scripts option for rtehtmlarea in the extension manager.

And, remove from typo3temp all files that start with rtehtmlarea. Clear the cache and Firefox, and you’re good to go!
