Others can weigh in, but (as with most software) the information of what all one needs to do & not do, in order to *not potentially* compromise anonymity while using Tor is quite spread out. It can take a long time for users to learn even the basics of what "else can go wrong," besides just installing TBB & hitting go. Yes, there's a short, basic list / FAQ that warns of some of these things. It's hardly complete or "sufficient for most users," IMO.On 08/14/2014 04:48 PM, Aymeric Vitte wrote:I am "defensive" because you seem to make a general case of something that can only happen in case of browser's/OS bug, and conveying to Tor users that they should not use js is a non sense, you make believe them that intrinsically js can easily leak their ip and/or mac addresses, which is wrong, this can happen under extraordinary circumstances that have nothing to do with js, here a windows/ff bug, which could have been a css attack or whatever. Regards,This was indeed an extraordinary circumstance. And it is misleading to focus on the importance of blocking Javascript. It's also evidence for using the latest Tor browser release, avoiding Windows, etc. However, I do see a "told you so" here. It's foolish to think that simply using the Tor browser is adequate protection for doing stuff where there are serious consequences. Maybe the the comment "Everything you need to safely browse the Internet. This package requires no installation. Just extract it and run." on the download page needs a "don't do stupid stuff" warning. Also, maybe the "Want Tor to really work?" section needs to reiterate the "don't rely on Tor for strong anonymity" warning. Maybe even something about firewall rules. Yes?
No doubt, anonymity w/ Tor is complicated - even for experts & putting together documentation (in one place) to cover most of the pitfalls is tough. But perhaps not impossible. Probably a better job could be done (than present) to revise / reorganize documentation on "what *else* you need to do / consider, to keep Tor more anonymous." Unfortunately, most users don't have the deep knowledge of Tor & TBB necessary to write correct, concise documentation for many of the more involved topics.

People who didn't allow javascript were safe.Because they managed to get in to the client browser, they could learn the real IP address and MAC addressand the color of your shirtWhy are you so defensive? Is it your code they broke? They could learn the color of my shirt if the browser user has access to a webcam, which is not uncommon. This is however highly irrelevant., they didn't learn this through Tor.Are you serious in your answer?Very much so. If you don't believe me, then maybe you'll believe these sources: https://lists.torproject.org/pipermail/tor-announce/2013-August/000089.html https://www.mozilla.org/security/announce/2013/mfsa2013-53.html Nothing was exploited through Tor. In fact, they couldn't find out who was using the server *because* people used Tor. So they had to resort to javascript exploits.
