I'm using Chrome as my default browser in Ubuntu 12.10. I need to use Firefox for business purposes (certain websites pertaining to my work only work with Firefox). Is there a way to force Ubuntu to use Firefox for certain types of URLs (maybe as defined by a regular expression) while maintaining Chrome as my default browser for all my other tasks? Perhaps as a shell script running in the background? I'd like this to work system-wide, covering links from Chrome itself as well as PDFs/ODTs, etc. I have searched for solutions, but I couldn't find anything besides OpenWith, a Firefox extension which adds a button to open certain links in other browsers which would again require me to open Firefox beforehand, which does not help me at all. Does anyone have any ideas? Something like Choosy for Linux?
