Extension broken in Chrome (Manifest V3) — fork with working MV3 migration available

[JoshuaKimsey]

The Problem

With Chrome fully transitioning to Manifest V3, The Printliminator no longer loads in modern Chrome. The extension uses two APIs that were removed in MV3:

• chrome.tabs.executeScript() (used ~7 times in src/chrome/popup.js)
• chrome.tabs.insertCSS() (used once)

The Web Store listing (nklechikgnfoonbfmcalddjcpmcmgapf) is still up but installs a broken MV2 extension.

The Fix

I've forked the project and migrated it to Manifest V3. The migration is complete and verified working in Chrome:

• manifest_version 2 → 3; browser_action → action; added scripting permission; web_accessible_resources converted to object form
• All chrome.tabs.executeScript/insertCSS calls in popup.js converted to chrome.scripting.executeScript/insertCSS (code: → func:, result[0] → result[0].result, explicit tabId targeting)
• Replaced the 2015 Grunt 0.4 build pipeline with a zero-dependency Node/sass build
• Functionally identical to v4.0.5 on normal pages

Fork: https://github.com/JoshuaKimsey/The-Printliminator
Tag: v5.0.0

A PR with these changes will follow this issue.

Offer

If anyone at CSS-Tricks/DigitalOcean is interested in reviving this project, I'm happy to:

• Transfer the migration work back upstream (the PR is ready)
• Help maintain it here
• Or continue maintaining the fork independently — just want to make sure the work is discoverable either way

The extension is LGPL-3.0, so redistribution with attribution is permitted. Original authorship (Chris Coyier, Devon Govett, Rob Garrison) is preserved in the manifest author/contributors fields and the README credits.
