Where you get it from decides how much everything after it is worth.
Download it from the Tor Project site. Not from a mirror, not from a software portal, not from a link somebody forwarded, and not from a search advertisement. A modified copy looks and behaves exactly like the real one right up until it does something you did not want, and there is no way to tell by looking.
Paid search results for browser downloads are a known route for modified copies. Typing the project address into the bar takes three seconds and removes the entire problem.
No extensions, no ad blockers, no privacy add ons, nothing. Tor Browser is configured as a whole so that users look alike. Every addition makes yours more distinguishable, which is the opposite of what it is for. An extension that promises more privacy delivers less by existing.
Updates carry security fixes and the browser handles them on its own. A version left alone for months is the most common preventable weakness on a machine that is otherwise set up carefully.
