1. Adjust left/right padding on buttons to 20px
2. Browser logo should persist at 60px below the top of the page through every step (currently the page shifts up on the importer screen)
3. Page background (default mode) should be #F9F9FA, same as toolbar background.
4. Top/bottom padding of the top site tiles on the importer screen is too much. Reduce to 20px
5. Clicking "Start Import" should not progress to New Tab until the importer wizard is completed.
6. Incorrect font-family. Should be using Metropolis.

Opened Bug 1641651 for adding Metropolis as font-family. Bug 1639723 addresses Click of "Start Import" should not progress to New Tab until the importer wizard is completed.

Updated patch that fixes failing test. Thanks

https://hg.mozilla.org/mozilla-central/rev/be5b74fc5731

I have verified the following using Firefox Beta 78.0b9 (Build ID: 202000619002543) on Windows 10 x64:

• Left and right padding for buttons is 20px.
• Browser logo has 60px top-margin on the importer page.
• Page background is #F9F9FA.
• Clicking the "Start wizard" does not progress to "about:home" unless the "Import wizard" is completed.

However, @Punam, I've noticed that the top margin for the top sites tiles is 20px, whilst the bottom margin is 26px. According to comment 0 it should be 20px for both top and bottom. Is this something that you reconsidered or would you like me to file a bug for this?

Note: I've attached a screenshot with the bottom margin.

Hi Robert, margin around tiles should be fixed with https://bugzilla.mozilla.org/show_bug.cgi?id=1644614. Thanks!

Thank you @Punam!
Based on the verification done in comment 9 and the fact that the top and bottom margin changes for the top sites tiles are tracked in this bug, I'm marking this issue as VERIFIED.
