Did not work at all, complete waist of time.

Didn't work at all... Just said something like "no information for this site"... for every site i tested

Lovely idea, but dangerously - needlessly - insecure. Don't install this. Every single website you visit is sent to Trustpilot in real-time, which is probably not what most people expect, and it is an immense security leak. Gavin, can you perform the request when a trust-score is explicitly requested instead, as people expect? The extension-icon tool-tip says "Check Trustpilot" after all, but that's not what it does; it just shows the information it already fetched in the background. Looking up the Trustpilot score only upon clicking on the icon would completely eliminate this problem. Please make this change. I understand that doing this would incur a minor delay as the score isn't preemptively fetched, but I think people would find that preferable to leaking all domains visited. If you really find this intolerable, make it configurable with a clearly visible checkbox, ideally defaulting to the safe behavior. This extension would be absolutely brilliant if this change was implemented. It's an excellent idea, and the presentation is really nice and succinct. It has other minor problems as others have pointed out (only checking the UK site at the time of writing), but I think with enough traction, Gavin could add more sites. To other readers: Verify this unsafe behavior for yourself: Open the browser console (ctrl+shift+j), set 'Console Mode' to 'Mutiprocess'. Mark 'Requests' and 'XHR' (i.e javascript requests), then filter on 'trustpilot'. Observe the log as you go to various websites. This review was written when the latest extension version is 0.1.1 - if a newer version exists, please check the behavior yourself and add a comment if this concern is no longer relevant! I really hope that the extension is updated so that I can leave a positive review and - more importantly - be an extension I will use.

Is Check Trustpilot Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Check Trustpilot requires a few sensitive permissions. Exercise caution before installing.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Check Trustpilot is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
