Anywho, I'm trying to add resume functionality to the firefox extension but I'm having some trouble. I decided to double-check with your batch script to just make sure that resuming is actually working cause your script has always worked for that, but it doesn't seem to be working atm.
Here's the output from the batch script:

Downloading normally works fine though. It's just the resume that's borking for some reason.
