Firefox has a lot of "clicking" sounds for me at the start of most samples. Like one instant square wave with no length.
Plays super laggy for me if it's an unfocused tab in firefox.

In terms of the clicks and pops, if it's not an imposition, could you let me know if you hear similar artefacts in the Newgrounds game listed in the FAQ? That MOD file was specifically modified to try and minimise that issue and I'd be interested in if it sounds better or worse on your setup.
I've dealt with this problem in a MIDI webapp I've developed a couple of years ago (midiano.com). If I remember correctly, firefox had some issue when samples were scheduled to immediately start with a gain value above 0. I believe the solution was to schedule them slightly earlier with a gain value of 0 and using "gainNode.setValueAtTime" to make the sound appear at the desired time.
Not entirely sure if that was the exact solution but I do remember firefox causing some problems in that regard. I just recall it being a hacky solution and that I couldn't find a documented explanation of why it happened.
Edit: midiano.com is excellent! Super useful to be able to visualise MIDI's that way.
Also: Thank you! The idea is definitely derived from Synthesia but that isn't free anymore and I wanted to make it work in a browser :)
