How to install Microsoft Edge extension (addon) in Chrome

I was able to load an extension from the Microsoft Edge-Store into Google Chrome successfully using the following steps.

1. Install the extension from the Edge-Store using the Microsoft Edge browser. Specifically, I used the Microsoft Rewards extension.

2. The url contains the extension ID, in this case bnplfnhcidhhdapmblniehfaaompjlck. Look for a folder with the extension ID in the following location:

   C:\Users\<username>\AppData\Local\Microsoft\Edge\User Data\Default\Extensions
   

3. Copy the folder with the extension ID to somewhere else, lets say your Desktop. In the folder you copied, open the manifest.json file in a text editor.

4. In your editor, delete the lines with "key": and "update_url": and save the file.

5. Open Google Chrome, navigate to the extensions page chrome://extensions and check to enable Developer Mode.

6. Click Load unpacked and select the folder with the extension ID you copied earlier.

This worked for this specific extension with my specific setup. The extension activated immediately and could be pinned and interacted with.

Tested using:

• Microsoft Edge v88.0.705.81
• Google Chrome Canary v91.0.4434.0
• Microsoft Rewards Edge Add-on

In Developer Mode you will be notified if there was an error with the extension or it simply would not load. This is useful if you try this with other extensions.

With browser extensions today being built using the WebExtensions API, extensions should for the most part be cross-browser compatible between Chrome, Edge, Opera and even Firefox somewhat.
