Two different language versions of Firefox at once?

I'm running Windows 7 Home Premium. I have two user accounts, one for me and one for my wife. She uses Firefox (Japanese), and I've been using another browser. But I'd like to start using Firefox (English).

Is there any way to run two different language versions of Firefox on the same computer? I want to be able to run both at the same time...(So if I'm surfing and she wants to check an auction quickly she can without my having to shut down my browser).

Can it be done with relative ease?

Make sure that each of you has their own Firefox profile folder.

See:

You can add -no-remote to the command line to open another Firefox instance with its own profile and run multiple Firefox instances simultaneously.

You can install extra language packs and set the general.useragent.locale pref to the language code (ja for Japanese) on the about:config page.

You can install such a language pack in the profile folder or possibly globally with a little more effort to have them for all users (profiles).
Best is to install the en-US version of Firefox in this case.

Firefox Win32 language packs:

Thanks...but is there any way to install two separate instances? I'd like to be able to customize...she likes themes and I don't, for instance. I like seeing a really clean interface and she like toolbars...I'm hoping we don't both have to use the same browser.
