really interesting stats Rated 5 out of 5 stars

for what it does this is by far the nicest, most informative and accurate solution I’ve found on the market. Alexa killer all the way…I’ve used their site in the past but having one-click access to so many statistics (for me, particularly the referrals and similar sites) is an enormous help and boost in productivity. Loyal and happy customer here - thank you!

One of the most useful extensions on FF Rated 5 out of 5 stars

the recent update was great, they took it from just showing similar sites to basically all of a site’s Google Analytics stats, from referrals to geographic break-down, et cetera. Its incredibly revealing and really helps my research (I’m a student). Recommended all the way. Also, its really light and doesn’t seem to affect my browser's performance.

must-have addon Rated 5 out of 5 stars

Great for doing web marketing, web discovery, and lead generation. Lots of useful data presented cleanly.

When something is free, it is you the product!
This is so very true in this case.
Do not use this at work on your internal corporate LAN. It will get a lot of sensitive information out and make it available for all on the Web.

This review is for a previous version of the add-on (3.1). 

Not Dangerous…

Hello Timok,

I'm really sorry you feel this way and I'd like to alleviate some of your concerns. We collect absolutely no personal data about you or your browsing habits. That being said, some usage statistics, 100% encrypted and anonymous, are collected and as you see in the description for this add-on, we are very transparent about this.
If you have any concerns, you can see exactly how our data is used at www.similarweb.com/website/amazon.com

Thanks for quick fix for developer. Rated 5 out of 5 stars

UPDATE: Thanks for quick fix :-)

Bug Fix Submitted, Awaiting Review

Hey Tilki!

This is actually not related to the Mac. On Friday there was an issue in the mechanism that fetches the data, which affected both Windows and Mac on Opera, Chrome, and Firefox.

We have already submitted a new version of the extension that fixes this issue, it is currently being reviewed by Firefox. It should be released in a day or two and auto-update for you.

I am really sorry about the inconvenience. Thank you for the heads up and being a customer!

PS: Once it is fixed I would appreciate if you reconsider your rating :-)

The interface in this new version leaves something to be desired. Primarily because when you click on a "similar link" it opens up an entire new window. Previous versions had a drop down menu of similar sites and was more user friendly IMO.

Why did I not find this sooner? Rated 5 out of 5 stars

Whoa this is great. I can now use this to find similar sites for various sites. Example Comic → Other Great Comics. Works better then what I was expecting.

Ganke nyttig redskap for å finne relevante nettsteder sentrert om et tema. Ikke alltid perfekte resulteter, men alt i alt er det mulig å gjøre kjempebrajobb med dette.

The icon for this add-on is too big when you put the toolbar icons in small, could make two versions of icon one big and one small. In this image imgur.com/h5inn you can see.

El icono de este complemento es muy grande cuando se ponen los iconos de la barra en tamaño pequeño, podrían hacer dos versiones del icono una grande y otra pequeña. En esta imagen imgur.com/h5inn se puede ver.
