Status: RESOLVED INVALID

(Firefox :: Extension Compatibility, defect)

Description

[Joshua Washburn]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2) Gecko/20100115 Firefox/3.6 (.NET CLR 3.5.30729)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2) Gecko/20100115 Firefox/3.6 (.NET CLR 3.5.30729)

The feature that allows tabs to separate from their original browser windows seems to have a debugging message enabled for when a tab is dropped onto the conent area. The message produced is 'TypeError: dt.getData("application/x-moz-tabbrowser-tab").linkedBrowser is undefined'.

This is not reproducible when it is dropped outside the browser window.

Reproducible: Always

Steps to Reproduce:
1. Setup: Open a new tab.
2. Reproduce: Drag newly created tab into the content area.

Actual Results:  
The message mentioned in "Details" appears.

Expected Results:  
The message should have been suppressed, as the separation still occurred.

I was running Tab Mix Plus at the time. I will post a message when I attempt to reproduce with it disabled.

I have narrowed it down to the "Split Browser" addon, which I did not think was relevant. It is only reproducible with that addon. I will notify the developer.

Thanks Joshua for tracking down that problem and notifying the add-ons author!
