Preview in Browser options

I recently had to reinstall Firefox and had both regular and Developer editions on my system. Before reinstalling the standard version, I had the Developer version as a selection in the Preview in Browser. Since the reinstall, however, I only have the standard Firefox.

I couldn't track down any setting to change this, as I would much rather use Developer edition when previewing rather than standard. There wasn't anything helpful on the Firefox site, either, so hopefully I can get some help here!
