Comment 49 for bug 481541

An option to force Firefox to remain on the background would be nice, that way
you could just click all links (in a message, for example) and then switch to
Firefox instead of clicking a link, switching the focus back to the email client
after Firefox steals it, click another link etc.

I've attempted to set the Summary to catch as many duplicate bug filings as
possible, since this request has popped up repeatedly in bugs in which it does
not belong.
