Browser extension that strips Google Analytics (UTM) tokens from URL query strings

Tracking Token Stripper

This is a Chrome and Firefox browser extension that strips Google Analytics (i.e. Urchin Tracking Monitor) tokens from URL query strings. This is done before the web request is made and results in both more private browsing as well as more aesthetically-pleasing URLs.

Install from the Chrome Web Store or Firefox Add-ons.

The following Google Analytics query string parameters are stripped:

• utm_source
• utm_medium
• utm_term
• utm_campaign
• utm_content
• utm_cid
• utm_reader
• utm_name

This extension requires these permissions:

• webRequest, to use the chrome.webRequest API
• webRequestBlocking, to use chrome.webRequest in a blocking fashion
• http://*/*?*, to filter http URLs
• https://*/*?*, to filter https URLs
