1394373 - Add option to duplicate tabs into different window for browser.tabs.duplicate()

Status: NEW

(WebExtensions :: General, enhancement, P5)

Description

[YUKI "Piro" Hiroshi]

To duplicate tabs into different (new) window, we need to do these steps:

 1. Open new blank window.
 2. Duplicate tabs in the old window.
 3. Move duplicated tabs to new window.

because browser.tabs.duplicate() doesn't provide ability to do them at a time.

https://developer.mozilla.org/en-US/Add-ons/WebExtensions/API/tabs/duplicate
https://developer.chrome.com/extensions/tabs#method-duplicate

However, the promise returned by browser.tabs.duplicate() is resolved after all duplicated tabs are completely loaded, thus we have to wait for minutes between the step 2 and 3. It is painful and dangerous, because the user can close the blank window before all duplicated tabs are ready.

So I propose a new option to duplicate given tabs into different window, like:

var duplicatedTabs = await browser.tabs.duplicate([1, 2, 3], { windowId: 5 })

How about this?

This is reequired by Tree Style Tab to implement its feature: duplicate a tree as a separate window.

OK, I'll join to IRC.

By the way, another similar bug 1394376 ls already triaged as wontfix on Fx57. I need one of them on Fx57, for painless migration...

Just to be clear on timelines, neither of those bugs will be happening in time for 57.

I’m interested in fixing this but I’m not quite sure where to fiddle in browser/components/extensions/parent/ext-tabs.js and browser/components/sessionstore/SessionStore.sys.mjs. Where and what should I do to duplicate (“restore”) the tab in a new window?
