good extension, though a privacy risk Rated 4 out of 5 stars

i like it a lot, but to have it pinging HMA servers all the time, its a great way to see what IP's you are using! Otherwise, great addon!

The review giving 1 star lie :))

This apps does what it is said to do for free, and well (even its looks are sightly).
Then it offers a pro-grade VPN service, that comes for a fee, like ALL VPN services in the world (if you want them to work).

No lies, no cheating, and Mozilla should sometimes find the time to remove dishonest reviews.

Doesn't actually work. Rated 1 out of 5 stars

Doesn't do anything unless you give them your credit card and pay a monthly fee.

Absolute lie. No option to hide IP at all

When you click it takes you to registration site. Oh the irony of having to register your details to stay anonymous,

This is what I'm looking for. It shows your IP, flag and the IP is selectable for a copy&paste. "Andavanced details" shows your location in Google map. "Log&Alert" is something I don't use so I can say nothing about it. "Hide my IP" is the only part you've to pay for. It brings you to hide my ass! no free addon but I cannot see any part forcing to use it. So I don't understand the previous complaint about not free addon. This is a IP checker and for what I can see it's free.

False advertising, it says FREE but you have to pay in order to make it work. Liars.

Hi, This Add-On is Really a Comprehensive Tool, With Answers from any aspect, Thank you developer for sharing this with us,..Additionally This Add-On(HMA! IP Checker) and (Your Current External IP) [1.for "Alert Me When IP Changes" feature((It popups a message that locking Firefox till clicking Ok on it) consists of previous IP address and current IP address and (sound alert) when IP changing but unfortunately by automatic feature after few minutes, around 1 hour it takes to check periodically my IP address till notices the changes. 2.for "Refresh IP Address" feature that can immediately check the real current IP Address but manual) are my fixed tested add-ons...Actually I'm beginner to judge about HMA! IP Checker, and I don't know many of its advanced featuers, but I like it, also flag and map options are helpful.."For Me This Add-On is Important Because I Everyday Use VPN Proxifier, So Just A Mistake (for example 5 minutes working with my restricted country IP address) Can Be Risky For Me... That's Why HMA! IP Checker Is My Fixed Everyday Add-On.
Just to say personally thank you :)

Hope to see your more & more successes.
Kind Regards,
Mahyar
