Add-on summary

This extension will automatically remove tracking elements from URLs to help protect your privacy when browsing through the Internet.

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

Why use this extension as opposed to similar ones? Most other “link cleaners” employ about a dozen rules when looking for tracking parameters to remove. ClearURLs utilizes over 250 rules, so its capabilities are more comprehensive. And ClearURLs is open source, so everyone can join in to the project and/or can check the source code to error or malicious code.

While this is a very good extension, I have found that for some wild reason it disables google sheets from allowing you precisely resize columns and rows

A whitelist would be nice. It may exist, but the FAQ on the homepage is 404. This breaks Google Sheets and leads to funkiness on some other platforms.

Does exactly what it advertises. Perfection. Goes well with other addons.
