CloseReview for XUL/Migemo by Nightingale
Rated 4 out of 5 stars
Pretty nice add-on with a few things to improve.
I looked for a plug-in for regexp-based search for quite long. It's implemented nice in this plug-in, but it's not convenient to use it on big documents from a quick find bar because it tried to highlight things after each character is typed in the bar and it's quite slow. What would be nice is having some delay after something is typed before search is started. Then I could type many letters quickly without slow-down.
