I think this is really a feature request, but I didn't see a forum for that. I used to use firefox almost exclusively, but switched to chrome when I started freelancing for a couple of different companies -- the identities feature of chrome really helps me keep my sanity by having a unique identity for each company. However, an issue has recently developed with chrome that made me switch back to firefox. The profiles feature in firefox seems to have gotten a lot better since I made the first switch, and I'm pretty happy with how it works ... with one exception: With firefox, clicking on a link in a different application always opens in the default profile. With Chrome, it would always open in the browser window that was most recently active. This is a very intuitive behavior, as whatever I am doing in the other application (e.g. thunderbird, evernote, skype) is almost always related to whichever browser window I had opened last. Any chance of this getting implemented? Or maybe there's already a way to do this? I found the following related topics, but neither helped with this question: https://support.mozilla.org/en-US/questions/981608?esab=a&as=aaq https://support.mozilla.org/en-US/questions/983341?esab=a&as=aaq
