1847276 - [about:welcome] Make Embedded Migration wizard variant 1 design default experiment

Status: VERIFIED FIXED

(Firefox :: Migration, task, P1)

Description

[Mimi Jung]

Variant 1 of the Embedded Migration Wizard experiment performed better and as a result we'd like to make this the default experience for about:welcome.

Variant 1 - all import options available by default, no + button
Variant 2 - all import options are hidden under + button/need to be expanded

See designs for a visual of both variants.

Bug 1847276 - [about:welcome] Make Embedded Migration wizard variant 1 design default experiment

Beta/Release Uplift Approval Request

• User impact if declined: Treatment-a designs (expanded) performed better with imports in a recent experiment. Treatment-b (non expanded) is currently the default experience as of 116 - we'd like to update to the layout that performed better with our users.
• Is this code covered by automated tests?: Yes
• Has the fix been verified in Nightly?: No
• Needs manual test from QE?: Yes
• If yes, steps to reproduce:

• Route to about:welcome
• Route to import screen (on easy setup flow select the "import" checkbox and continue)
• Notice the lack of expanded menu option (no + button, all available import options will be visible by default)
• Resize to <800px and confirm layout renders all available options without overflow
• Route to about:preferences and search "import" select Import Data, notice variant 2 designs (non-expanded, has + button, import options not visible by default)

(Steps can also be found in the test plan in the Phabricator patch)

• List of other uplifts needed: 1847815 which is required for this patch as it decouples the pref used to change the layout for about:welcome
• Risk to taking this patch: Low
• Why is the change risky/not risky? (and alternatives if risky): Both layouts have been QA'd in Fx116 and in the experiment which included the layouts as different treatment branches. The layout change itself is minor (expanded vs non-expanded) and is covered by tests.
• String changes made/needed: N/A
• Is Android affected?: No

I have verified this task using the steps provided in the Test Plan and I can confirm the following:

• The expanded variant of the "Embedded Import Wizard" Onboarding screen(all the options are visible and there is no "+" button) is displayed on the "about:welcome" page.
• All the elements from the Onboarding Import screen are successfully rendered and there is no overlap if the browser is resized <800px.
• The non-expanded version (the options are collapsed and the "+" button is displayed) of the "Import Wizard" is displayed if the Import Data button from the "Import Browser Data" section of the "about:preferences#general" page is displayed.

Verified using the latest Firefox Beta 117.0b8 (Build ID: 20230815180041) and the latest Firefox Nightly 118.0a1 (Build ID: 20230816094547) installed on Windows 10 x64, macOS 13.4.1, and Linux Mint 21.1.
