Focus on element triggers browser menu
<p>I'm use jQuery 1.9.
When I programmatically set focus on input element (textbox) in Firefox or any other browser and press T it activates Tool menu in menu browser (similiar is for B(Bookmark) and so on). When I try to write K... text starts inside focused input element. Element has a focus, I see cursor. When I click with the mouse and try to write T or B is appears inside textbox.</p>

<p>So, I want to write any combination inside textbox after programmatically set focus on element. Where is the problem? What to do?</p>
