URL Modification

Privacy Browser includes the following URL modifications, which are enabled by default.

Google Analytics

Google Analytics has the option to add campaign parameters to URL for tracking purposes. Each one of these parameters starts with utm_. 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_ or `&utm forward, turning the URL into:

https://www.example.com

Facebook Click IDs

Facebook adds a click ID to the URL of outbound links. An example URL looks like this:

https://www.example.com?fbclid=IwAR0tRuonn7ashvzlE4GtsiHn-D--mfFUWLd0qD8JrD8xsVTJKx2DIcVCNFo

Privacy Browser strips out anything from the ?fbclid= or &fbclid= forwared, turning the URL into:

https://www.example.com

Twitter AMP Redirects

Twitter has a system where, if they detect a mobile user agent, they automatically direct users to AMP versions of outbound links. This is done by appending &amp=1 to the end of their redirect URLs. For example:

https://t.co/2nTJCML891?amp=1

Privacy Browser strips out anything from the ?amp=1 forward, turning the URL into:

https://t.co/2nTJCML891
