Even works within the Windows version of FireFox 3.6.3, installed in the same bottle.
One oddity, though, was that it began to run a bit slower than normal and seemed to stop working once. I'm not sure where the problem was (perhaps it was something unrelated, even). After killing it, I checked System Monitor and noticed that my CPU usage was abnormally high, but I'm still not sure from what. After rebooting now, it seems to be operating normally without any trouble. So, assuming it could have just been something else with the glitch above, I gave it a gold rating.
Note: The Linux version of FireFox seems to handle things a little differently. It doesn't seem to want to open it within the browser like the Windows one does, but rather download it then open it separately in Adobe.
