Here is the fiddle
After alert fires popup box we click on "OK" button and if we start moving our mouse up or down without clicking it starts to selecting text like as if we have been pressing button on a mouse to select text. Looks like I have this behavior only in Firefox.
How can I disable it?
Here is the js code:
$('#test').on('blur', function() {
alert('test');
})
Tried on Mac and Windows - getting the same behavior.
Mac's Firefox ver. 43.0.4 Window's Firefox ver. 41.0.2
