In order for us to test under-search-bar snippets, we should make the AS devtools collapsible. That way we can observe the actual behaviour of snippets etc.

Iteration: --- → 68.3 - Apr 15 - 28

Heads up that once this lands in nightly, if you have browser.newtabpage.activity-stream.asrouter.devtoolsEnabled set to true you will see a button show up in the top left hand corner of the new tab page (see attached screenshot).

QA steps

  1. Set browser.newtabpage.activity-stream.asrouter.devtoolsEnabled to false. Open about:newtab. Ensure you do NOT see a yellow button in the top left hand corner.
  2. Set the above pref to true. Ensure you now see a button that says "Expand Devtools".
  3. Click the button. The button should now say "Collapse Devtools". You should see the devtools appear on the page. Ensure they are working normally and you can scroll.
  4. Click the button again. Ensure you now see the regular new tab page and can scroll.
  5. Set browser.newtabpage.activity-stream.asrouter.devtoolsEnabled to false again. Ensure you see a regular new tab now and that the yellow button disappears.

Regression testing

Please also check snippets are working normally in both settings of the devtools pref.
