I am student at university and use university internet. I am interested in using Tor to prevent my university from seeing what sites I visit and what I am doing on those sites. As I understand it now, if I use tor my university can see that I am using tor but not what sites I visit/what data is on those sites. Is that correct? Also, I have heard that is bad practice to install extensions like adblock on Tor or to login into websites on Tor as it can de anonymize you. However if I just want to hide my traffic from my university this should not be a problem as long as I do not log into any university services correct?
