I hereby request the development of, or a pointer to a Firefox plug-in that prevents the focus (active window or tab) from being taken away from the page or tab that I am currently on, with no exceptions.
I can’t count how many times I’ve been typing, reading, or scrolling, and something else gets the focus. Then, I have to go back to where I was.
Even if the focus just shifts for 1/2 a second, that is annoying because then the letters I typed suddenly get lost, or my SHIFT-Click no longer has the first item selected, or whatever.
So, Firefox Plug-in or about:config setting that prevents the focus from being changed unless manually changed by the user. Find it, then let me know.
