Test your add-ons for Multi-process Firefox compatibility

You might have heard the news that future versions of Firefox will run the browser UI separately from web content. This is called Multi-process Firefox (also “Electrolysis” or “e10s”), and it will improve browsing performance for your users.

If your add-on code accesses web content directly, using an overlay extension, a bootstrapped extension, or low-level SDK APIs like window/utils or tabs/utils, then you will probably be affected.

Multi-process Firefox is scheduled for release in the next few months, so we urge you to test your add-ons for compatibility.

  • If it breaks in Multi-process Firefox, your users will be impacted, and you will need to update your add-on. You can find documentation on how to make them compatible here.
  • If it does not break in Multi-process Firefox, you will need to flag it as compatible in the install manifest.

    A notice: The links to MSN pages should include the segment /en-US/ to prevent ‘Not Found’ errors when redirecting to non-existent localized pages…

    Which timezone is that schedule for?

      It should automatically display the correct time blocks, whatever time zone you’re in.

      Sorry, we forgot to update the information. Last Tuesday (and this whole week) there’s a big Mozilla event and most employees were unavailable. The office hours should resume next week.
