Details

User Agent: Mozilla/5.0 (Windows NT 6.3; rv:38.0) Gecko/20100101 Firefox/38.0
Build ID: 20150806103657
Firefox for Android

Steps to reproduce:

Call WINAPI functions:
SystemParametersInfo(SPI_SETDRAGWIDTH,0,NULL,0);
SystemParametersInfo(SPI_SETDRAGHEIGHT,0,NULL,0);

Restart the Mozilla Frefox and try to move tabs using mouse.



Actual results:

The drag operation is not possible.

The calling SystemParametersInfo with flag SPIF_UPDATEINIFILE will permanently block the drag operation in firefox. Thus the bug is major. 



Expected results:

The drag operation shall be possible with prompt start of operation.
