As another 1-star review stated, you collect and sell users' personal information, and yet you state that you thought you were being very up front, very clear about the fact that you do. Tell me then, on your MAIN PAGE in Mozilla Extensions, are you saying that you are being up front about it just because the LINK TO your license agreement is listed just above the following? "This extension does not capture any information or usage analytics at all." Can you REALLY not see how people would be lulled into a false sense of security by the above-quoted statement? And please: DON'T come arguing semantics just because the word 'collect' is absent, when the word 'capture' in the quoted statement in question is used instead, because even a fool with only a rudimentary knowledge of the English language could catch that! I would ask what you would expect most people to think, but you will likely hide behind something to the effect of you not being able to help the person who is stupid enough to not read the terms of a semi-binding license agreement and that you have deceived no one in any way... technically. And, in most cases, YES people should read license agreements but when you put 'This extension does not capture any information or usage analytics at all.' in the very next line just below the link to your agreement, well, let us just say that it IS most certainly more than enough to turn around and bite you and were it a more serious matter, while you certainly could win, there is more than a shadow of a doubt that you are being purposely deceptive.
