windows¶
Note
These APIs are for the main Thunderbird windows which can contain webpage tabs and also other window types like composer or address books that cannot contain webpage tabs. Make sure your code interacts with windows appropriately, depending on their type.
Use the browser.windows API to interact with Thunderbird. You can use this API to create, modify, and rearrange windows.
