1.Do not use personal social accounts.  networks
I do not recommend logging into your personal account on Vkontakte, Facebook or any other social network.

Any anonymity system has its flaws.  Online anonymity software can hide the IP address and location, but large social.  networks and do not need this information.  They already know the user, his friends,

2. Do not go to accounts that you use without Tor
Be aware that the following data is saved in the server log on each visit:

Client IP address / location.
Date and time of the request.
The specific addresses of the requested pages.
HTTP code.
The number of bytes transferred to the user.
User’s browser agent.
You can issue your account even with a single authorization through a connection that is not protected by Tor, from a real IP address.  As a result, such single mistakes lead to dire consequences.

3. Do not log into online banking or payment systems
Also, I do not recommend going to an online bank or payment systems (Qiwi, YandexMoney, PayPal, etc.).  In most payment systems, using Tor entails an account freeze due to “suspicious activity”.  The reason is that hackers sometimes use Tor for fraudulent activities.

4. Don’t send sensitive data without finished encryption
Tor’s most vulnerable point is exit nodes, they can be eavesdropped on communications and mediated attacks (i.e. when a third party secretly participates in relaying or changes the way data is transmitted between two users), even if you use HTTPS.  Therefore, the only way out is to use finished encryption.

5. Don’t use the same digital identity for too long
The longer you use the same nickname, the more likely you are to stumble and give yourself away.  As soon as the attacker has such an opportunity, he will be able to study the history and all activity under this pseudonym.  Create new digital identities and stop using old ones.

6. Do not stay logged in to social networks and other accounts longer than necessary
Reduce the time of authorization in social.  networks and other services associated with accounts to the absolutely necessary minimum.  After logging out of your account, it is safe to change the Tor chain.  This is necessary because many websites have social media integration buttons.  Therefore, if the user remains authorized in any service, then these buttons tell the owner of the service to visit the site.

7. Do not use a regular browser and Tor at the same time
Using both a non-Tor browser and a Tor Browser at the same time, you risk one day to confuse them and get burned.

When using clearnet and Tor at the same time, there are also risks of simultaneous connections to the server via anonymous and non-anonymous channels.  The user can never feel safe visiting the same page at the same time.  Many different sites are hosted in the same cloud.  Services like Google Analytics are featured on most sites and therefore see many anonymous and non-anonymous connections.

8. Do not share your link first
Never be the first to advertise your anonymous project!

The more the personalities are separated from each other, the better.

9. Don’t open random files and links
If you have been sent a file of any type or a link to a file, be careful regardless of the file format.  The sender, mailbox, account or key could be compromised, and the file or link could be specially prepared to infect the user’s system when opened in a standard application.

10. Don’t use mobile phone verification
Many websites ask for a mobile phone number when you use Tor.  In no case do not give out this information only if you have some kind of alternative like a virtual number.

Any phone numbers will be logged.  The SIM card will most likely be tied to the user.  Even if not, receiving SMS will give you the location.  You can try to buy a SIM card anonymously, but the risk is still the phone.  If the SIM card is purchased anonymously, but the phone is not, then there will be no anonymity, because the two serial numbers will be linked together.

There are two options:

1) Buy anonymously a SIM card and a phone, go away from home, receive an SMS and immediately turn off the phone.

2) Use online services to receive SMS messages, but many of these services are not suitable for some websites and applications.
Finally, I want to say that the most effective way to stay anonymous is to use multiple means of anonymity together, not just Tor Browser.  Monitor your online habits closely and be careful.
