[Affected Versions]:

• Firefox Beta 98.0b9 (Build ID:20220224185616)

[Affected Platforms]:

• Windows 10
• Linux Mint 20.2
• macOS 11.6

[Prerequisites]:

• Be enrolled in the Validate Private Browsing Mode (pbNewtab) as experimentation surface experiment. You can do this by:
• Setting browser.search.region to US “from about:config”
• Setting nimbus.debug to true “from about:config”
• Navigating to the following URL: about:studies?optin_slug=validate-private-browsing-mode-pbnewtab-as-experimentation-surface&optin_branch=control

[Steps to reproduce]:

1. Open the browser from prerequisites.
2. Open a Private Browsing window (Ctrl + Shift + P).
3. Right click the "Stay private with Mozilla VPN" button.
4. Click the “Open Link in New Tab” option.
5. Navigate to “about:telemetry” and search for the following event: category: aboutprivatebrowsing | method: click |object:promo_link.

[Expected result]:

• The event is recorded if the link is opened in another tab.

[Actual result]:

• The event is NOT recorded if the link is opened in another tab.

[Notes]:

• The issue is also reproducible for the keyed scalar (aboutprivatebrowsing#click#promo_link).
• The issue is also reproducible for the “Learn more” link (event category: aboutprivatebrowsing | method: click |object: info-link and keyed scalar aboutprivatebrowsing#click#info_link).
• The issue is also reproducible at middle click or when using “Open Link in New private Window”.
• Attached is a recording of the issue.

One possible solution is to use button styled as link so that context menu can be hidden. Nice to fix in future marking P3 for now.

Marking won't fix as we are not tracking telemetry from this entry point
