Answer 1

Firefox will only obey requests to raise a window if a security option is set, and it's not set by default. Chrome won't pay attention to focus() requests at all, as far as I can tell. Safari does obey focus() request.

The specific Firefox setting is in the "Tools" -> "Options" ("Edit -> Preferences" on Linux, maybe MacOS) dialog. There's a "Content" tab, and in that there's a checkbox for enabling Javascript. Along with that is an "Advanced" button that brings up another dialog, wherein one finds a checkbox to allow (or disallow) the raising and lowering of windows by page code.

edit: Here is a test page: http://gutfullofbeer.net/focus1.html and you should be able to see that Firefox will raise a window when the page calls window.focus(). You must either have the browser set up so that new windows (created with window.open()) open up in a new separate window instead of a tab, or else you can tear off the tab of the secondary page when it opens.

I had the same problem, i though there was a problem with my JS script, after a long search i have found a solution:

1) In a new tab, type about:config in the address bar and press button "Enter". Click the button "I accept the risk!" in order to confirm the warning

2) In the search field, type dom.disable to get dom.disable_window_flip

3) If the property dom.disable_window_flip is true, double-click it to switch the value from true to false
