tracklessURL is an open-source privacy-focused extension that automatically removes tracking parameters from URLs before they're visited. Using the declarativeNetRequest API, tracklessURL is able to function without requiring intrusive permissions.

Features:

• Frequently updated built-in list of the most common URL trackers, such as UTM (Urchin Tracking Modules) parameters, Facebook trackers (fbclid), and multiple other social media and marketing website trackers.

• Fully user-customizable: Simple, intuitive user interface allows you to add your own rules for blocking parameters. Delete, edit, toggle, or group rules together at any time.

• Global whitelist feature provides an easy way to whitelist any websites that may behave incorrectly because of parameter removal.

• Multiple ways to add rules: Add a parameter manually by specifying the parameter to block and the websites to block it on or paste a URL containing tracking parameters to quickly add new rules to block them.

With tracklessURL, I hope to build and maintain the web's largest list of URL tracking parameters. Few lists currently exist, and none are near comprehensive enough. If you find parameters to add to the built-in list, please contact me with the information. The GitHub repository for tracklessURL can be found at https://github.com/col1010/tracklessURL.

Some of the tracking parameters tracklessURL removes include:

Google: Urchin Tracking Modules (utm_source, utm_medium, etc.), gclid
Facebook: fbclid
Instagram: igshid
Piwik: pk_campaign, pk_keyword, etc.
Reddit: share_id
Youtube: si, ab_channel, feature, etc.
Matomo: mtm_campaign, mtm_source, etc.
Microsoft: msclkid
Olytics: oly_enc_id, oly_anon_id
Spotify: si, context
Vero Marketing: vero_id
Marketo: mkt_tok
LinkedIn: trackingId, refId, trk, etc.
Mailchimp: mc_cid
HubSpot: hsa_cam, hsa_src, _hsenc, etc.
Bronto: _bta_tid, _bta_c

And many more!
