1075941 - Moving a tab with swapBrowsersAndCloseOther fails with e10s enabled

Status: RESOLVED DUPLICATE of bug 918634

(Firefox :: Tabbed Browser, defect)

Description

[Peter J. Sloetjes]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:35.0) Gecko/20100101 Firefox/35.0
Build ID: 20141001030205

Steps to reproduce:

My extension Monitor Master makes use of the browser utility function "swapBrowsersAndCloseOther".


Actual results:

This function fails with e10s enabled.


Expected results:

The code in swapBrowsersAndCloseOther or a function it calls (swapFrameLoaders?) probably needs a minor change to become compatible to e10s.

I think this will hopefully just end up being a dupe of bug 1029750, but I guess it's possible that a fix there won't fix this directly if they rename functions, so marking a dep for now.

It would be so nice if the awesomebar automatically removed bug links that were dupes from its list.

Comment 3

[Dave Townsend [:mossop]]

Bug 918634 is the root cause here I think.

Comment 4

[David Parks [:handyman]]

The patch in bug 918634 handles this.

I am still getting NS_ERROR_NOT_IMPLEMENTED browser.xml:1210 when calling swapBrowsersAndCloseOther with e10s enabled. 

browser.xml:1210
--------------------
this.QueryInterface(Components.interfaces.nsIFrameLoaderOwner)
              .swapFrameLoaders(aOtherBrowser);

Fx 46.0a2

Please file a new bug with a minimal testcase, ideally something to run from the browser console or somesuch.
