Manifest V2 extensions won’t run in Chrome in January ~~2023~~ 2024.

https://developer.chrome.com/docs/extensions/mv3/mv2-sunset/

According to https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/manifest.json/manifest_version no browser except Chrome supports V3. Not sure what one’s supposed to do. Update: Firefox 109 supports v3.

This article gives some clues: https://discourse.mozilla.org/t/when-will-web-ext-support-manifest-v3/91514/5. Sounds boring.

Found a checklist: https://developer.chrome.com/docs/extensions/mv3/mv3-migration-checklist/

Might be able to piggy-back on learnings from refined-github/refined-github#5531

web-ext now has --firefox-preview for trying experimental manifest v3 support: https://github.com/mozilla/web-ext/releases/tag/7.1.0

Update: Newer blog post from Mozilla: https://blog.mozilla.org/addons/2022/10/31/begin-your-mv3-migration-by-implementing-new-features-today/
