Use when reviewing HTML source and JavaScript for links or resource URLs pointing to domains listed in common adblocker filter lists.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Blocked Tracking Links When a navigation link's URL matches a tracking domain pattern, the adblocker may block the request entirely — the user clicks the link and nothing happens, breaking core site functionality. ## Quick Reference - Adblockers block URLs matching domain-level filter lists like EasyList and EasyPrivacy - Affected resources include external scripts, images, fonts, and API endpoints hosted on blocked domains - Analytics and tag management scripts (Google Analytics, GTM, Hotjar, Heap) are commonly blocked - Self-hosting or proxying external scripts through your own domain bypasses most domain-level blocks - 20–40% of desktop users have an adblocker installed — blocked analytics skews your data significantly ## Check Identify external script sources, image src URLs, iframe src URLs, and anchor href values that point to known tracking domains (googletagmanager.com, hotjar.com, facebook.net, doubleclick.net, etc.). Test whether these resources load successfully with uBlock Origin enabled. ## Fix …

How to install
mdr add thedaviddias/front-end-checklist/blocked-links@sha256:12f7067bfcde987cThe line at the top of this page pins the label git:20261004.4b0ddb9, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
