I know this sounds like a huge request, but it also sounds like it could be a huge success.
Would it be possible to have mIRC sort of "embedded" inside a tab in Firefox in the form of an extension? All of mIRC could be contained in one tab in Firefox. The basic layout could maintain the same structure (main window, nickname list, server/channel button bar, etc), but it would just be placed inside Firefox.
What would the purpose of this be? Well, quite simply to just integrate things together into one, neat little package. The less programs I have running, the happier I am. I constantly switch back and forth between IRC and my browser... and I just think it would be really cool to have it all in one place.
Clicking links in mIRC would just open new tabs in FF.
What do you think?
