In short answering to the original post:
Nothing to worry about. Don’t modify Tor Browser.
Hello so I decided to do a DNS leak test while on Whonix I tried 3 different sites the first was http://www.dnsleaktest.com/ which said that I was on an anonymous server. Then I used www.ipleak.net which said I was in Canada but still no leaks.https://www.whonix.org/wiki/Stream_Isolation
Then I tried http://www.ip-check.info which gave me the strangest results.Forget about https://www.whonix.org/wiki/Ip-check.info.
HTTP sessuin: 10 minutes until your tor identity is changed. Rating: Medium
Referer: Original websites may see what website you are coming from Rating: MediumForget about https://www.whonix.org/wiki/Ip-check.info.
I use a browser spoofer on the clearnet is that tool also working on tor?No. Whonix/Tor is not influenced by the underlying network connection. It works or it does not work.
Is that why it says my tor ID will be changed in 10 minutes?Tor circuits expire by Tor design. This is normal. Forget about https://www.whonix.org/wiki/Ip-check.info.
How can I get a higher rating on the referer section so that websites can't see where I am coming from.Tor Browser deals with that. Modifications recommended against.
Forget about Browser Tests - Whonix.
Either read through all the existing discussions referer spoofing on torproject.org, agree with them or if applicable, make an educated argument, or leave it as is.
Why did my location differ between websites?Different browser tabs are isolated from each other. Stream isolated. (https://www.whonix.org/wiki/Stream_Isolation) Likely end up with different exit relays. Nothing to be worries about.
