Japanese popup translators are not working in FF.

I'm receiving emails in Japanese. I use the Zimbra webclient on Firefox 3.0.3 (both on WinXP SP3 and Mac 10.5). My Japanese isn't great, so I'm trying to get a couple of Firefox popup translator addons (rikaichan and Perapera-kun) to work.

On websites with Japanese characters, (ie. Yahoo! JAPAN), the addons work great. Just hover the mouse over a word, and a popup appears with the translation. But they both don't work at all in the Zimbra webclient. I.e. mousing over doesn't do anything.

Anyone know of a way to get those addons to work or a way around this?
Or can this be done through a zimlet? (I never wrote a zimlet or FF addon before)

Getting these plugins to work would be a big help.

Looking further into this, I glanced over the Firefox add-ons (just downloaded & renamed the .xpi files to .zip, and .jar to .zip and looked). There's a lot of javascript that Firefox add-ons seems to be using.

I'm guessing somehow Zimbra is not allowing the Firefox add-on's javascript to run. If that's right, I'm further guessing that a zimlet needs to be created to match the features of the addon.

Is there a way to get Zimbra webclient to allow the Firefox add-on's javascript to run?
