I tested this add-on scrupulously and it is well done Rated 5 out of 5 stars
I tested it for two days (48hrs) and noticed that in most cases My Public IP worked flawlessly. Congratulations.
How did I do this? I typed in google "what is my ip-adress" or "my ip please". The results I compared scrupulously with the results of this add-on. Far above 90% was a match! This add-on is highly recommended.
