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

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
