802819 - FF16 - Tab drag and drop to new window leaves tab behind (tearing off a tab duplicates it to a new window, not moves there)

Status: RESOLVED INCOMPLETE

(Firefox :: Tabbed Browser, defect)

Description

[gerry]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:16.0) Gecko/20100101 Firefox/16.0
Build ID: 20121010144125

Steps to reproduce:

Under Win 7 x64 Pro: I had a browser window opened with multiple tabs. I dragged one of them to the desktop and a new window was created. 


Actual results:

The tab still existed in the original window. Furthermore, the tab in the original window could not be closed and when I typed a a search into the google toolbar in the new window, the results showed up in the original window. I exited the browser and tried this again, and the same thing happened. This behavior is new to FF16 - under FF15 this did not occur.


Expected results:

The tab should have been completely removed from the original window.

Please, could you try the basic troubleshooting steps:

1) Safe mode: https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode

2) New profile: https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles

The culprit is maybe an incompatible extension. Does it fix your issue?
