A TOR browser is safe, all it does is route your traffic through several relays that both hide your location, and then even better - encrypts everything you do, type or look at - within the browser.
Your ISP (company that supplies your internet) can see everything you do, not that anyone is looking, but it can if it wants to. All of your activity is logged at least for a set time.
Using a TOR browser encrypts and hides what you do within their browser - not even your ISP can see it. All they can see is that you use a TOR browser
As far as hackers, it is no more or less dangerous than any browser.
Only if you use it to go to the dark web.
I'm not going to take a shot at TOR as it has its purpose. I will suggest though, with some degree of confidence, at least in my instance (which is separate from the average citizens, especially in the U.S as you have a defended Constitution and Bill of Rights); I am quite confident that the IP address reflected as one
but it was clear my true IP address was local.
How I know is not important but I can assure you that my activities were redirected and/or not reflective of what TOR showed. In fact, there were multiple indicators.
Now, the encryption aspect is important in regards to say, using a Whistleblower site (I was going to post some examples but I refrain) or other such sites. However, I am confident that they are fully aware that I have visited the site
but they are not aware of what I shared (which was most important to me).
Correct though, for the average citizen, especially in the U.S; you probably have more privacy. Regardless, it is safe to use for general, innocuous interests/privacy. Browsers after all are simply in essence, HTTP translators. TOR translates from a source that is distant and is encrypted via onion I believe.
Bear in mind, you can't use java or similar extensions via TOR. As a hint, this was one indicators of many I employed to test what was going on. As usual, the Creepy Ones couldn't help but expose themselves in all of their moral deficiencies. For what purpose? Ask them...
