Review for XUL/Migemo by Trasd
Rated 3 out of 5 stars
I also downloaded it for RegEx, but did get it to work. For RegEx (haven't tried the other modes) you must turn off "Show position of found terms..."
I would suggest to the developer that the three modes be separated into different add-ons for easier development (and should work together). The ideas are good, but it tries to do too much with a single add-on.
To create your own collections, you must have a Mozilla Add-ons account.
