Every server in the Tor network is maintained and operated by a volunteer. Since you can never know the person behind each relay, Tor can never be completely secure. While an exit node won't find your location or identity, it can spy on your activity. Therefore, when using Tor, you should be careful of visiting unsecured websites or using Tor Browser with plugins installed.
When you use the former, your data gets protected by end-to-end encryption and is a lot faster than Tor. However, some VPN providers log your browsing history, making it easier for online surveillance to take place.
Tor Browser, on the other hand, is highly-secure and protects your browsing activity from all prying eyes. With the right settings and an additional VPN, using Tor Browser can offer excellent anonymity and privacy.
Offering online privacy and a chance to avoid censorship, the security of the Tor Browser is unparalleled. However, it does have its drawbacks, like its slow speed. Tor Browser is a powerful and effective tool that keeps your data secure and private. It allows Tor users to bypass censorship laws, advance freedom rights, and avoid surveillance by law enforcement officials.
The popular privacy technology is free and perfectly legal to download and use. While the browser has its limitations, it does protect user privacy and maintains anonymity. The volunteer-run project is highly-secure and offers services that allow users to take back their online freedom.

If you run Tor Browser and another browser at the same time, it won't affect Tor's performance or privacy properties. However, be aware that your other browser is not keeping your activity private, and you may forget and accidentally use that non-private browser to do something that you intended to do in Tor Browser.
Only Tor Browser's traffic will be routed over the Tor network. Any other application on your system including other browsers will not have their connections routed over the Tor network, and will not be protected. They need to be configured separately to use Tor. If you need to be sure that all traffic will go through the Tor network, take a look at the Tails live operating system which you can start on almost any computer from a USB stick or a DVD.
We do not recommend running multiple instances of Tor Browser, and doing so may not work as anticipated on many platforms. Please be sure no other instance of Tor Browser is already running, and that you have extracted Tor Browser in a location that your user has the correct permissions for. Tor Browser is a modified version of Firefox specifically designed for use with Tor.
A lot of work has been put into making the Tor Browser, including the use of extra patches to enhance privacy and security. While it is technically possible to use Tor with other browsers, you may open yourself up to potential attacks or information leakage, so we strongly discourage it.

Tor Browser in its default mode is starting with a content window rounded to a multiple of px x px to prevent fingerprinting the screen dimensions. The strategy here is to put all users in a couple of buckets to make it harder to single them out. That works so far until users start to resize their windows e.
Tor Browser ships with a fingerprinting defense for those scenarios as well, which is called Letterboxing , a technique developed by Mozilla and presented in It works by adding white margins to a browser window so that the window is as close as possible to the desired size while users are still in a couple of screen size buckets that prevent singling them out with the help of screen dimensions.
In simple words, this technique makes groups of users of certain screen sizes and this makes it harder to single out users on basis of screen size, as many users will have same screen size. Tor Browser can certainly help people access your website in places where it is blocked.
Most of the time, simply downloading the Tor Browser and then using it to navigate to the blocked site will allow access. In places where there is heavy censorship we have a number of censorship circumvention options available, including pluggable transports.
For more information, please see the Tor Browser User Manual section on censorship. Sometimes websites will block Tor users because they can't tell the difference between the average Tor user and automated traffic. The best success we've had in getting sites to unblock Tor users is getting users to contact the site administrators directly. Something like this might do the trick:. I tried to access your site xyz. I urge you to reconsider this decision; Tor is used by people all over the world to protect their privacy and fight censorship.
By blocking Tor users, you are likely blocking people in repressive countries who want to use a free internet, journalists and researchers who want to protect themselves from discovery, whistleblowers, activists, and ordinary people who want to opt out of invasive third party tracking.
Please take a strong stance in favor of digital privacy and internet freedom, and allow Tor users access to xyz. Thank you. In the case of banks, and other sensitive websites, it is also common to see geography-based blocking if a bank knows you generally access their services from one country, and suddenly you are connecting from an exit relay on the other side of the world, your account may be locked or suspended.
If you are unable to connect to an onion service, please see I cannot reach X. Tor Browser often makes your connection appear as though it is coming from an entirely different part of the world. Some websites, such as banks or email providers, might interpret this as a sign that your account has been compromised, and lock you out.
You may be able to avoid this scenario if your provider offers 2-factor authentication, which is a much better security option than IP-based reputations. Contact your provider and ask them if they provide 2FA. Sometimes JavaScript-heavy websites can have functional issues over Tor Browser.
The simplest fix is to click on the Security icon the small gray shield at the top-right of the screen , then click "Advanced Security Settings Most antivirus or malware protection allows the user to "allowlist" certain processes that would otherwise be blocked.
Please open your antivirus or malware protection software and look in the settings for a "allowlist" or something similar. Next, exclude the following processes:. Finally, restart Tor Browser. This should fix the issues you're experiencing. Please note that some antivirus clients, like Kaspersky, may also be blocking Tor at the firewall level. If you downloaded Tor Browser from our main website or used GetTor , and verified it , these are false positives and you have nothing to worry about.
Some antiviruses consider that files that have not been seen by a lot of users as suspicious. To make sure that the Tor program you download is the one we have created and has not been modified by some attacker, you can verify Tor Browser's signature. You may also want to permit certain processes to prevent antiviruses from blocking access to Tor Browser. You might be on a network that is blocking the Tor network, and so you should try using bridges.
Some bridges are built in to Tor Browser and requires only a few steps to enable it. Under the "Bridges" section, select the checkbox "Use a bridge", and choose the "Select a built-in bridge" option. From the dropdown, select whichever pluggable transport you'd like to use. Once you've selected the pluggable transport, scroll up and click "Connect" to save your settings.
In the "Bridges" section, select the checkbox "Use a bridge", and from the option "Select a built-in bridge", choose whichever pluggable transport you'd like to use from the dropdown. Your settings will automatically be saved once you close the tab. If you need other bridges, you can get them at our Bridges website.
For more information about bridges, see the Tor Browser manual. One of the most common issues that causes connection errors in Tor Browser is an incorrect system clock. Please make sure your system clock and timezone are set accurately. If this doesn't fix the problem, see the Troubleshooting page on the Tor Browser manual. Sometimes, after you've used Gmail over Tor, Google presents a pop-up notification that your account may have been compromised.
The notification window lists a series of IP addresses and locations throughout the world recently used to access your account. In general, this is a false alarm: Google saw a bunch of logins from different places, as a result of running the service via Tor, and decided it was a good idea to confirm the account was being accessed by its rightful owner.
Even though this may be a byproduct of using the service via Tor, that doesn't mean you can entirely ignore the warning. It is probably a false positive, but it might not be since it is possible for someone to hijack your Google cookie. Cookie hijacking is possible by either physical access to your computer or by watching your network traffic. In theory, only physical access should compromise your system because Gmail and similar services should only send the cookie over an SSL link.
In practice, alas, it's way more complex than that. And if somebody did steal your Google cookie, they might end up logging in from unusual places though of course they also might not. So the summary is that since you're using Tor Browser, this security measure that Google uses isn't so useful for you, because it's full of false positives. You'll have to use other approaches, like seeing if anything looks weird on the account, or looking at the timestamps for recent logins and wondering if you actually logged in at those times.
More recently, Gmail users can turn on 2-Step Verification on their accounts to add an extra layer of security. This is a known and intermittent problem; it does not mean that Google considers Tor to be spyware.
