Chrome's Manifest V2 removal pushes legacy clipboard managers off the Web Store

A phase-out that finished on schedule

Clipboard manager extensions are among the clearest casualties of Google's completed Manifest V2 phase-out. According to a write-up on dev.to, users of these tools have this year either watched them stop working or found them quietly removed from the Chrome Web Store, and the article walks through both the timeline and what to look for in a replacement.

The post, citing Google's official schedule, dates the rollout in three steps. On March 31, 2025, Manifest V2 extensions were disabled by default for all Chrome users, though they could still be re-enabled. On July 24, 2025, with the arrival of Chrome 138, they were disabled everywhere and re-enabling was no longer possible. On August 31, 2026, the remaining Manifest V2 extensions were pulled from the Chrome Web Store altogether. Installs still running on Chrome 138 or earlier keep working for now, the article says, but they receive no updates and cannot be reinstalled once removed.

Why clipboard managers suffered more than most

The dev.to piece argues that clipboard managers were hit harder than the average extension category. Many of the well-known ones were written years ago against Manifest V2 background pages, and a large share had been abandoned long before the migration deadline, so a Manifest V3 version never arrived. The result, the author writes, is that a lot of people moved from a tool that quietly worked to a dead one, with no notice from the developer.

What to check in a replacement

Manifest V3 clipboard managers are not interchangeable, the post cautions, and it offers a five-point checklist before installing one:

• Content type. Most new clipboard managers handle text only. Anyone who copies images or formatted text should verify support up front.
• Capture scope. Many extensions only monitor copying inside web pages; text copied in other applications may reach the history only when the extension popup is opened, or not at all.
• Data handling. Clipboard history is sensitive, so the post favors extensions that keep it on the device, with no account and no analytics, and that exclude password fields and Incognito windows from capture.
• Retrieval. A searchable history, pins for frequently reused clips, and JSON or CSV export keep the archive usable and prevent lock-in.
• Limits. Check the free tier's history size and pin count before committing a daily workflow to it.

A disclosure to weigh

The article then recommends one specific replacement, Clipstay, while disclosing that its author is an AI assistant to Clipstay's developer, so that section reads partly as promotion. As described, Clipstay saves text copied or cut on web pages, supports search, pins and one-click re-copy, keeps data local, excludes password fields and Incognito windows, and offers free JSON or CSV export. Its stated limits: text only, web-page capture rather than system-wide, and a free plan capped at the 100 most recent clips plus 5 pins.

Why it matters

The Manifest V2 sunset has been years in the making, but its impact is still reaching ordinary users, and the extensions breaking are the ones with small or vanished development teams. Clipboard managers are a useful illustration: built on APIs that Manifest V2 allowed and left unmaintained, they failed silently rather than migrating. There is also a privacy dimension, since clipboard history can hold passwords and other sensitive strings, which makes vetting a replacement more important than a casual install. The practical takeaway from the dev.to post is to confirm what a new manager captures, where the data lives and whether its developer is candid about limitations, and to treat any extension that has not been updated since the migration as likely to fail.
