macos - How can I always open certain URLs/domains in certain browsers?

My main browser is Firefox, so I want most URLs to open there when I've clicked on them from Thunderbird. But I want to look at Google+ in Chrome, where it's faster; likewise a few other JavaScript-heavy sites.

Is there some way to hijack the Mac's "default browser" launcher so that it will parse the URL and route the request to my favorite browser for that URL? I can think of three ways this might happen:

• Create a Mac app that acts as the default browser that does nothing but go launch another browser, depending on the URL;


• Set Firefox as my default browser, and use some extension (like the discontinued Safari View or Open In Safari, or the windows-only Chrome View or IE View) to redirect specific URLs to Chrome;
  
  
  
  • Set Chrome as my default browser, and use some equivalent extension to redirect specific URLs (including a wildcard URL) to Firefox.
  
  
  
  

Any ideas?
