you may find that it becomes an invaluable addition to your developer toolkit

That's exactly what happened for me. I still prefer Opera (I paid for it - both to eliminate ads and to support an independent browser company) as my regular browser. But with just a few extension, FireFox has replaced a whole bunch of other applications that I used regularly for R&D in the past.

So now, most of the time, I have both browsers open -- Opera for my regular browsing and FireFox for ripping apart competitor's pages.
