How to have one browser use a different Network Connection?

Hi experts, long-time reader, first-time poster.

Here's what I'm trying to do:

I'm at work - I have two active network connections, one is my work LAN, and one is my phone tethered via USB. Both show up in Network and Sharing Center as active and connected to the internet. All of my network activity, including all internet browser usage, currently defaults to the work LAN connection (as it should).

Is there a way to get one of my browsers (i.e. Firefox) to connect to the internet via my tethered phone connection, while everything else stays connecting through my work network? I know there's a way to set priority for the network connections, but unfortunately setting that priority affects everything, not just web browsing.

I'd be very interested to see what you all come up with on this. Thanks in advance!

You can try using Connectify Dispatch Pro for this dual connection. It's supposed to allow this type of connection configuration, using two at once on the same PC.

Perfect, thanks Chev, I will check it out now.

Just want to say that Connectify does exactly what I need. Thanks Chev!
