Description

[Ciprian Georgiu, Desktop QA]

Found in

Affected versions

• Nighly 156.0a1
• Beta 155.0b1

Tested platforms

• Affected platforms: Win 11, macOS 26 and Ubuntu 26.04

Preconditions

• browser.smartwindow.autoTabGrouping.enabled = true
• browser.smartwindow.enabled = true

Steps to reproduce

1. Launch a Smart Window.
2. Open a couple of pages related to news from the same domain, e.g. bbc.com
3. Open a couple of pages related to games from the same domain, e.g. ign.com
4. Click on the Oranize tabs button from the toolbar.
5. Create two tab groups.
6. Click on the "View Tab Groups".
7. Delete one group.

Expected result

• The View tab groups sub-panel remains since one group is still created.

Actual result

• The View tab groups sub-panel is dismissed even though one group is still created.

Regression range

• N/A

Additional notes

• As a user, I expect to see the remaining groups in the sub-panel after deleting one, without needing to reopen the tab groups sub-panel.
• I'm not sure if the current behavior is the expected one.
