Extension hosting

  • Article

Most extensions are published to the Microsoft Edge Add-ons website, to protect users from malicious extensions.

Publish options for extensions

All extensions are distributed to users as a special archive (.zip) file with a .crx suffix. Extensions published to the Microsoft Edge Add-ons website are uploaded as .zip files. The publishing process automatically converts the .zip file into a .crx file.

The following two scenarios don't require you to publish your extension in the Microsoft Edge Add-ons website:

  • Extensions that are distributed using Enterprise policy.
  • Using unpacked extension directories on a local machine when Microsoft Edge is in developer mode.

In both cases, Microsoft Edge periodically checks extension hosts for new versions of installed extensions and automatically updates them without user intervention.
