Let's say I created some tooltip which displays a popup when the cursor is placed over a given part of the page, and removes it when I move the mouse. For an example, see http://jsbin.com/aCoboQo/1 and try to put your mouse over the popup.
I now wish to troubleshoot it and need to check the CSS using Firebug or some other similar tool.
It would be nice to somehow lock the browser after the popup is shown, so then I could navigate to the popup (and not have the popup disappear) and inspect the HTML and CSS.
Is this possible with any standard browser (ie, chrome, firefox/firebug, etc)? If so, how?
