browser addons - Using vim as the editor for the It's All Text! Firefox Add-on

I am trying to use vim as the external editor for It's All Text! within Firefox. This works fine for standard http:// web pages, but when I try to use it within TiddlyWiki, 89 instances of vim are opened. I am guessing that the difference is that the TiddlyWiki page is a file on my local file system. I also created a simple html file and had the same problem. Is there a way around this problem?

From the comments:

I am on Windows Vista if that makes a difference.

Answer

Try the vimperator plugin for firefox. Hitting CTRL+i within a textarea form will vim start as external process. This works almost everywhere - at least where I tried.
