Bugzilla

 I‘ve verified this enhancement using the latest Firefox Nightly 104.0a1 (Build ID: 20220725094920) on Windows 10 x64, macOS 12.3.1, and Linux Mint 20.2 x64.
- If Firefox is not pinned, the “Pin Firefox to taskbar” intro screen is displayed. The Firefox browser is pinned to taskbar/kept in Dock after clicking the “Pin Firefox to taskbar” primary button, and the “Set as default” screen is shown (if the browser is not set as default)/ “Colorways” screen (if the browser is set as default).
- If Firefox is pinned and it is not set as default, the “Set as default” intro screen is displayed. 
  - The “OS settings” window is displayed and the “Import data” slide is shown after clicking the primary button.
  - The “OS settings” window is not shown and the “Import Data” slide is displayed after clicking the secondary button.
- If the Firefox is pinned and set as default, the “Get Started” intro slide is displayed. After clicking the primary button from the “Get started” screen the “Colorways” slide is displayed. The “MR Gratitude” slide is displayed after clicking either the “Set colorway” or “Skip this step” button.
  - The “See what’s new” button is present in the “MR Gratitude slide” and clicking it redirects to Firefox View page, and the “about:newtab” page is displayed after clicking the “Start browsing” button from the “MR Gratitude” slide.
