An amazing feature provided for free. I do have a problem a small problem with it though; The relay icon displays notifications using an exclamation mark, but it used this notification to promote a discount... always terrible to see, I don't want notification telling me to buy products. While I get that I'm using this for free and all so you could say this is the price for the product, I don't beleive annoying your user into buying the product is the right way to do it, I especially didn't expect it from mozilla which I so highly respect as an organisation. Aside from the slight annoyance, there was also a bug with the notification. The notifcation symbol didn't go away after I opened upon the notification, and I couldn't see anything else on the extention that looked like a notification so I assume that was all.

While I did rant a bit about it, I do still think this is a great extentision that adds great security and utility.
