An Essential Firefox Addon Rated 5 out of 5 stars
Regular Expressions Tester is a fantastic add-on! It's on my short list of essential Firefox add-ons. The ability to check data as you type it is pure gold. It's also nice and compact. I also like that its highlights that parts that match. I've tried other regex apps and none of them are as goodThis review is for a previous version of the add-on (18.104.22.168-signed.1-signed).
