Rated 5 out of 5 stars

Great idea! It works in the most cases for words in english language but not always for another language, for example german letter ß could not be recognized as ss. It still needs improvement. Maybe authors could try to implement the SoundEx algo: http://en.wikipedia.org/wiki/Soundex .There is a extension called SearchWP that uses this algo in the source code, but its source is not complete yet. The Find-box and the Find-toolbar of the default theme FF3 became much smaller as it was, it is hard to see what i type in there. Better leave all those cosmetic things to be default.

This review is for a previous version of the add-on (0.1).
