Are we e10s yet?

To test an add-on:

  1. Confirm that the add-on works as expected in Firefox's Release channel before testing Nightly. :)
  2. Install Firefox Nightly.
  3. Install the add-on you would like to test.
  4. e10s is enabled by default in Firefox Nightly, but disabled in Firefox's other release channels: Developer Edition, Beta, and Release. When e10s is enabled, Firefox's tab tool tip is suffixed with "- e10s".
  5. Confirm that the add-on still works as expected with e10s in the Nightly channel.

If the add-on works as expected, click the add-on's "it works" link to tell Mozilla!

If the add-on does not work as expected with e10s, click the add-on's "Report bug" link. Please include a description of what you expected to happen, what actually happened, and steps to reproduce the problem.
