Open issues/risks

• How does this impact the quick filter bar toggle? Where should this button be placed?
• How does this impact add-ons that assume that the menubar will be available across all tabs? Do such add-ons exist?

Stage 1: Definition

1. Feature overview

As part of our ongoing UX refresh in Thunderbird, we'd like the tabs to be placed above the main Thunderbird menubar. This is similar to what has emerged in common browser UI over the past few years.

This should be toggle-able, so that users can move the tabs back below the menu bar, preserving the current Thunderbird UX.

2. Users & use cases

This change would affect all users of Thunderbird.

We want to support both tabs above and below the menubar, and careful thought will need to go into how this could impact add-ons that rely on the menubar being visible across all tabs.
