Please also note that this issue affects those opened Tabs after a session restore or restart, if the tabs are not loaded they are displayed in the Manage Tabs tool panel but the user cannot close those tabs.

firefox-release Uplift Approval Request

• User impact if declined/Reason for urgency: User won't be able to close unloaded tabs when the user sends a NL close tab prompt and confirms tabs to close.
• Code covered by automated testing?: yes
• Fix verified in Nightly?: yes
• Needs manual QE testing?: yes
• Steps to reproduce for manual QE testing: 1. Open several related tabs like Mac and Cheese recipes

2. Send a prompt in smart window - "Close open Mac and cheese recipes tabs"
3. Reload the window
4. Ask again the same prompt
5. Confirm the tabs wanted to be closed
6. The tabs should close as requested.

• Risk associated with taking this patch: low
• Explanation of risk level: It is low because we are using existing tab permanentKey instead of linkedPanel
• String changes made/needed?: no
• Is Android affected?: no

This needs a Beta uplift request also. For the future, note that in Lando, you can pick a target version now instead of a target branch and Lando will automatically create requests for all applicable branches for you.
