1356949 - Add to webextension api an event on tabs.doubleclick

Status: RESOLVED DUPLICATE of bug 1246706

(WebExtensions :: Untriaged, enhancement)

Description

[greg.luto]

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:52.0) Gecko/20100101 Firefox/52.0
Build ID: 20170321232041

Steps to reproduce:

I would like to request an event to be fired on double clicking on a tab handle.

There are many legacy extensions that use this to increase ui speed for certain actions
(https://addons.mozilla.org/en-US/firefox/search/?q=double+click&cat=all&appver=52.0&platform=linux)
for example to pin/close/reload/close-others.

It is especially helpful on laptops where middle click is more difficult and precision to hit the [x] for a window is hard. I would like this functionality to continue past version 57.

May also want to be included in discussion on "design and implement an API for toolbars" @ https://bugzilla.mozilla.org/show_bug.cgi?id=1215064

Thanks!
