You are receiving this email because you are a registered developer of a Firefox extension.

Starting with Firefox 100, Firefox will be requiring user activation to start an add-on install.  If you are distributing your add-on from a third party site, you may need to change your install flows.  If this applies to your add-on(s), we recommend that you test your install flow using Firefox 100.  Firefox 100 Beta can be downloaded from  mozilla.org.

If changes are needed, you will need to use one of the following approaches on your website:

  • Link directly to the add-on XPI using a standard Web link
  • From a user initiated event handler (such as a click handler) using window.location to point directly to the add-on XPI

Additionally, InstallTrigger.install will be removed as of Firefox 102.  This API was never officially supported in Firefox, and remaining users will need migrate to one of the above approaches.  In Firefox 100 and 101 this API will still be available, but will require user activation as described above.  We will also include deprecation warnings in the Web Console.

If you have any questions, please get in touch with us on our community forum on Discourse.
