I have been using it for more than a week and now am worried about the consequences that I am not sure are true or not!
I am worried that by allowing random users to surf using my network to prevent surveillance, someone will use my address to do malicious things, and I will get into legal consequences. Also, what if many services blacklist my IP address so eventually I get a lot of restrictions in my browing experience.
Furthermore, will this extension increase my fingerprint?
Are these thoughts valid, or am I just overthinking? If anyone knows, please comment.


You cannot get into legal trouble for snowflake afaik. Its only a bridge, not an exit node. This means that websites the other person visits will see the exit nodes public ip, not yours.
Running a vpn for snowflake will only slow down the other persons connection without giving you much better security.
If it helps I’ve been running snowflake on my main browser for about a year now with no issues (not saying this is definitive proof for anything though.)
Can the ISP see the websites the other person is visiting?
No, but they see that you are connected to a tor entry node and that someone is sending you data. From this they can conclude that you are running a tor proxy.
