It will install on 32 bit & 64 bit Linux. And on 32 bit version of Windows. And on the Intel versions of OS X.

P.S.> it only checks web sites that use HTTPS and not HTTP like BBR. If you want to play around and check out PERSPECTIVES options, you can go to »mail.google.com to test.

Suffern, NY | Re: Must have Firefox 3 to try it out said by fAcEtIOUs:Anyone wanting to test this add-on, it is for Firefox 3 only. If you have Firefox 2, it won't install. I'd love to upgrade to FF3 but every week or so when I bring it up to test, I get a long list of FF Extensions that still have not been made compatible with FF3 (or have a separate FF3 version). Once the list shrinks to only list those that I have installed but do not use, I will make the switch. Until then, I must stay with FF2 if I need the extension. | |
| | | | Although there is a 64-bit Linux version, it is still experimental and must be downloaded and installed manually. So I guess my Ubuntu 64-bit install will have to wait a bit to get this extension. | |

Mechanicsburg, PA | ?? longtime ff user on multiple machines. is this something that the average guy can install/use/understand? thanks, bub | |
| | | | Re: ?? said by ebubman:longtime ff user on multiple machines. is this something that the average guy can install/use/understand? thanks, bub I installed it in about 1 minute. The default options are fine. And if you want to experiment and modify options, that is very easy to do.
But this is a set & forget add-on. Once installed, it will only alert you to a problem if something is wrong when you connect to a HTTPS web site where you have been subject to a MITM attack or where the web site has been hijacked by a DNS attack. So most likely, most people will never see this addon do anything.

| Not sure how useful this really is This is only really useful if you go to publicly accessible » (SSL) pages with self signed certificates. I can count the number of these I've seen over the last 10 years on one hand.
The vast majority of encrypted pages are from large corporations (banks, credit cards, Google, Yahoo, etc) and they can afford to have valid certificates.

kudos:5 | Am I missing something? So how does having this "notary" prevent a man in the middle attack? If there is a man in the middle between me and my bank, for instance, why can't that same man be between this notary and my bank? | |

If there is a man in the middle between me and my bank, for instance, why can't that same man be between this notary and my bank? See pages 7 thru 9 of their paper where they discuss the statistical odds against pulling off a MITM attack against the client and also against the MULTIPLE notaries at the same time.

Franklin, TN | said by cdru:So how does having this "notary" prevent a man in the middle attack? If there is a man in the middle between me and my bank, for instance, why can't that same man be between this notary and my bank? It's based on the system of "how have things been" and "how have thing changed".
If your bank has always used the same certificate that doesn't expire for 8 years and one day at a coffee shop, the certificate has completely changed, but still "valid" as a MITM attack would do, it throws up an alert. I won't protect you from a MITM attack on the first ever visit to your banking website, only those afterward.
It's part of the problem computers have that humans tend to be better at. That's complete trust of strangers. If things look fishy, we get suspicious. Computers, they don't care, if 2 > 1, then they are happy. For us, when we see 2 > 1.5 we ask why 1.5 instead 1 like before?
