This extension is absolutely amazing. I consider it one of the very select "Absolutely Mandatory and Indispensable" extensions I always use. I truly do not know how I lived without it, before first finding it. I don't know why Mozilla isn't pushing this as one of the *Recommended* extensions, because it should. Maybe I'm overestimating the number of people who would be interested in launching a webpage from one browser directly into a specific other browser, but for those that ever do this more than occasionally, this thing is terrific. I love Open With so much.
