On my Mac, Safari is (still) my default browser. But as a web developer I also do a lot of work and testing in Chrome and Firefox.
When in Chrome or Firefox and using the 'Open and Fill' option these links are always opened in Safari (the default browser).
It would be very nice if Open and Fill uses the browser that is open and active at that time.
