Though there are some things you can practice to improve your anonymity while using Tor and offline.
Use Tor Browser and software specifically configured for Tor
Tor does not protect all of your computer's Internet traffic when you run it.
Tor only protects applications that are properly configured to send their Internet traffic through Tor.
Unfortunately many sites ask for more personal information than they need through web forms.
If you sign in to that website, they still don't know your location but they know who you are.
Further, if you provide: name, email, address, phone number, or any other personal information, you are no longer anonymous to that website.
The best defense is to be vigilant and extremely cautious when filling out web forms.
不要在 Tor 上 torrent
Torrent file-sharing applications have been observed to ignore proxy settings and make direct connections even when they are told to use Tor.
Even if your torrent application connects only through Tor, you will often send out your real IP address in the tracker GET request, because that's how torrents work.
Not only do you deanonymize your torrent traffic and your other simultaneous Tor web traffic this way, you also slow down the entire Tor network for everyone else.

Similarly, we do not recommend installing additional addons or plugins into Tor Browser, as these may bypass Tor or otherwise harm your anonymity and privacy.
Tor will encrypt your traffic to and within the Tor network, but the encryption of your traffic to the final destination website depends on that website.
To help ensure private encryption to websites, Tor Browser includes HTTPS-Only Mode to force the use of HTTPS encryption with websites that support it.
However, you should still watch the browser URL bar to ensure that websites you provide sensitive information to display a padlock or onion icon in the address bar, include https:// in the URL, and display the proper expected name for the website.

在线时不要打开通过 Tor 下载的文档
Tor Browser will warn you before automatically opening documents that are handled by external applications.
You should be very careful when downloading documents via Tor (especially DOC and PDF files, unless you use the PDF viewer that's built into Tor Browser) as these documents can contain Internet resources that will be downloaded outside of Tor by the application that opens them.

If you must work with files downloaded via Tor, we strongly recommend either using a disconnected computer, or using dangerzone to create safe PDF files that you can open.
Under no circumstances is it safe to use BitTorrent and Tor together, however.
Use bridges and/or find company
However, by default, it does not prevent somebody watching your Internet traffic from learning that you're using Tor.
If this matters to you, you can reduce this risk by configuring Tor to use a bridge rather than connecting directly to the Tor network.
Ultimately the best protection is a social approach: the more Tor users there are near you and the more diverse their interests, the less dangerous it will be that you are one of them.
