Pros
Pro The only browser package which includes a gateway built-in into TOR, a network where you can actually browse the web completely anonymously
Privacy. It's fundamental. And this browser has enabled and keeps enabling people to lookup things they don't want their ISP/ government or surveillance marketers to see.
And what's better they won't know a thing about what you searched.
What is visible to the outside world however is the fact: you make use of TOR and probably the TORBrowser this client / citizen of ours is using TOR to obfuscate his /her traffic (=~anonymize ).
Cons
Con Extremely slow
Caused by the tor network the browser depends on.
Con Too many supporters
Tor has so many supporters such as brave, which makes it more popular. This is another thing how tor will be unsecure.

Con Dangerous
Hackers may insert something illegal onto your computer and get you arrested.
