URL Modification

Privacy Browser includes the following URL modifications, which are enabled by default. Each of these queries are stripped out as well as everything that follows them.

An example URL looks like this:

https://www.example.com?utm_source=news4&utm_medium=email&utm_campaign=spring-summer

Privacy Browser strips out anything from the first ?utm_ forward, turning the URL into:

https://www.example.com
Tracking Queries

Privacy Browser blocks all the trackers listed at PrivacyTests.org as well as a few additional trackers that I have observed around the web.
