[Feature Request] Additional option for opening tabs

[goblinshredder]

After closing a tab opened using "Open link in new tab", the tab where "Open link in new tab" was used is activated. I don't need this. I would like an option to disable this. To do this, you don't need to set "openerTabId" in "browser.tabs.create".

The problem is, that omitting this will change the order in which the tabs are opened (if default is selected in the settings). Also users who use add-ons that display a tabs hierarchy like TreeStyleTab will lose the hierarchy.

I'm not sure if this is by design or a bug in Firefox, because if I open the new tabs via the context menu or middle mouse button then the next tab to the right will be focused. I probably could work around it, maybe the moveInSuccession API would be a good choice here. However I think this is not intentional by Firefox so it could be fixed there as well.
