ClearURLs is an add-on based on the new WebExtensions technology and is optimized for Firefox and Chrome based browsers.

This extension will automatically remove tracking elements from URLs to help protect your privacy when browse through the Internet, which is regularly updated by us and can be found here.

Application

Many websites use tracking elements in the URL (e.g. https://example.com?utm_source=newsletter1&utm_medium=email&utm_campaign=sale) to mark your online activity. All that tracking code is not necessary for a website to be displayed or work correctly and can therefore be removed—that is exactly what ClearURLs does.

Another common example are Amazon URLs. If you search for a product on Amazon you will see a very long URL, such as:

https://www.amazon.com/dp/exampleProduct/ref=sxin_0_pb?__mk_de_DE=ÅMÅŽÕÑ&keywords=tea&pd_rd_i=exampleProduct&pd_rd_r=8d39e4cd-1e4f-43db-b6e7-72e969a84aa5&pd_rd_w=1pcKM&pd_rd_wg=hYrNl&pf_rd_p=50bbfd25-5ef7-41a2-68d6-74d854b30e30&pf_rd_r=0GMWD0YYKA7XFGX55ADP&qid=1517757263&rnid=2914120011

Indeed most of the above URL is tracking code. Once ClearURLs has cleaned the address, it will look like this: https://www.amazon.com/dp/exampleProduct
