A solid 5 Stars Rated 5 out of 5 stars
This review is for 1.4.0 and replaces my previous reviews.
Linkificator is an actively supported extension and shows steady improvement between versions. The developer is responsive, takes bug reports seriously and is open to suggestions.
While there is still some room for ongoing improvement, I am comfortable giving Linkificator the highest 5-star rating. Also, I would like to thank the author for the add on and the ongoing support.
Good Job, Marka Pola!
Edit: 1.5.0 took care of most false positives.
