To help Mozilla out with this bug, here's the steps:

1. Comment here on the bug that you want to volunteer to help.
   This will tell others that you're working on the next steps.
2. Download and build the Firefox source code
   • If you have any problems, please ask on Element/Matrix in the #introduction channel. They're there to help you get started.
   • You can also read the Developer Guide, which has answers to most development questions.
3. Start working on this bug.
   • You'll need to add status = 5 before this switch statement in aboutDialog-appUpdater.js
   • You'll need to navigate to about:preferences and scroll down to the Nightly Updates section or search for "updates" in the search bar.
   • You'll need to replace this "https://nightly.mozilla.org/" <label> element with a <html:a> element. Note, you have to use <html:a> in this context because it is a XUL document and not a HTML document.
   • You may also need to update this Fluent file and replace the <label> with <html:a> if the link does not receive the correct text when the <html:a> is swapped in.
   • If you have any problems with this bug, please comment on this bug and set the needinfo flag for me. Also, you can find me and my teammates on the #reusable-components channel on Element/Matrix most hours of most days.
4. Build your change with mach build and verify your changes by making sure the link navigates correctly to "https://nightly.mozilla.org". Also check your changes for adherence to our style guidelines by using mach lint.
5. Submit the patch (including an automated test, if applicable) for review. Mark me as a reviewer so I'll get an email to come look at your code.
   • How to Submit a Patch
   • This is when the bug will be assigned to you.
6. After a series of reviews and changes to your patch, I'll push it to autoland.
   • If there are changes requested, please read the "To update a submitted patch" section to ensure you don't accidentally create a duplicate revision!
   • Your code will soon be shipping to Firefox users worldwide!
