2016147 - Notes are missing on Google results opened in Containers or Private Browsing

Status: NEW

(Firefox :: Tabbed Browser, defect)

Description

[Simona Badau, Desktop Test Engineering]

Attachment: Screen recording with the issue

Found in

• Nightly 149.0a1

Affected versions

• Nightly 149.0a1

Tested platforms

• Affected platforms: Windows 11 x64, Ubuntu 24.04 and macOS 15

Preconditions

• Google is set as the default search engine.

Steps to reproduce

1. Perform a Google search by entering a search term in the URL bar.
2. Add a note to the Google results page.
3. Right-click the tab and open it in a new container (e.g. @Personal).
4. Copy the Google results URL from the tab that has the note.
5. Open a Private browsing window.
6. Paste the URL and press Enter.

Expected result

• In both steps 3 and 6, the Google results pages should display the note added in step 2.

Actual result

• The note is missing on both the page opened in the new container and the one opened in Private Browsing. For more details, please see the screen recording.

Regression range

• Not a regression.

Additional notes

• An extra attribute is appended to the URL (e.g. &sei=q6KMaa_VOYeL9u8P963bmAg). If this attribute is removed, the note appears correctly in the affected tabs.
• The issue appears to be intermittent and is easier to reproduce on a new profile.

Notes are esentially lost (for a normal user), so I am raising severity to S2.
