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.

All functions in a nutshell

User reviews
I rather like the extension but as has been noted by others it breaks google sheets and also breaks google docs (albeit to a lesser extent). If this were fixed or a way provided to fix it, I would gladly give 5 stars and recommend to everyone.

Breaks Google Spreadsheet, with this addon enabled all charts from spreadsheet disappear. No way to whitelist spreadsheet domain so the only way is to disable the whole extension.
