So, very weirdly, within an hour of posting my question here it miraculously started working. I swear I didn't do anything to make this happen - didn't reboot my system, didn't disable add-ons, didn't update Firefox (was already using the most recent vers), didn't have any Windows updates. But, bam, it started working and had no trouble "attaching" to Firefox. Unfortunately, a new error just started occuring today and causing RTMPSuck to crash every time it tries to capture a C4 stream. Will have to start a thread on that one now! Thanks guys.
