Since the status are different for nightly and release, what's the status for beta?
For more information, please visit auto_nag documentation.

The patch for this bug removed a skip-if = fission annotation from browser/components/newtab/test/browser/browser_aboutwelcome_multistage.js and added a new test (browser/components/newtab/test/browser/browser_aboutwelcome_rtamo.js) with a skip-if = fission annotation. I'm going to assume that it was a mistake (not caught by reviewers), please be more careful. If it's not a mistake, please don't add new tests that are disabled for fission when they're added, and please don't reenable tests in an unrelated patch.

yes, it was mistake. Thanks for catching! We can file a followup fix unless this is getting fixed in another patch.

Hello,

Verified the fix using the latest Nightly (84.0a1/20201022215159) and Beta (83.0b3/20201022171613) under Windows 10 Pro 64-bit with the recommended add-on uBlock Origin.

The new RTAMO UI has been properly implemented. Clicking on the “Add the Extension” button will start the extension installation process and clicking on the “Not Now” button will open the Awesome Bar for browsing. See the attached screenshots for more details.
