[Notes]:
I am not sure exactly what is the issue here, or if there is an issue but here is what I have observed:

• The keyword unity triggers the unity3d.com Top Pick result, which doesn't have an icon. However, in the Top Picks json file, there is another entry for Unity website with the unity.com domain, which has an icon. See this screenshot.
• If I click the Top Pick results with unity3d.com domain I am redirected to the https://unity.com/, so I am not sure why there are two entries for this website, and how the redirect should work. Also one has an image and the other one doesn't.
• However this doesn't seem to be a Firefox issue, but I'm adding the versions and the platforms I have noticed this.

[Affected versions]:

• Nightly 114.0a1
• Beta 113.0b8
• Firefox 12.0.1

[Affected Platforms]:

• Mac 12.4
• Windows 10 x64
• Linux Mint 20

[Prerequisites]:

• Have a new profile with the following prefs set:
• browser.search.region to US
• browser.urlbar.quicksuggest.dataCollection.enabled to true
• browser.urlbar.merino.providers to adm,top_picks
• browser.urlbar.bestMatch.enabled to true

[Steps to reproduce]:

1. Open the Nightly browser with the profile from the prerequisites.
2. Type "unity" in the awesome bar.
3. Observe the Top Pick triggered.

[Expected result]:

• The "Unity Real-Time Development Platform | 3D, 2D, VR & AR Engine - unity.com" is triggered.

[Actual result]:

• The "Unity Real-Time Development Platform | 3D, 2D, VR & AR Engine - unity3d.com" is triggered.

[Additional Notes]:

• Attached is a screen recording of the issue.

Unity is removed from the Top Picks json file. Considering this I will mark this issue as Verified - Fixed.
