If voice notes, video messages, or media uploads are failing, or you keep seeing an “Extension bridge timeout” error, you may have two Kondo extensions installed at the same time. The older copy doesn’t auto-update and can interfere with the working one.
This only applies if you signed up before April 15, 2026. Newer accounts can skip this page.

How to check

Open your browser’s Extensions page (chrome://extensions, edge://extensions, or brave://extensions) in the same browser profile where Kondo is failing. If you see two Kondo entries, one is the duplicate to remove.

​
How to remove it

  1. Turn on Developer mode at the top of the Extensions page — this makes it obvious which copy is the unpacked one
  2. Find the Kondo entry labeled Unpacked (or Loaded unpacked, often shown as v1.10.3) and click Remove
  3. Keep the Kondo extension installed from your browser’s extension store
  4. Refresh your inbox tab
The remaining Kondo extension auto-updates on its own. If the Remove button is missing or disabled, the extension may be managed by your IT or browser admin — contact us and we’ll help.
