The loop tries to constantly read the streaming HTTP data. Firefox will
become unresponsive and will offer the user to stop the script.
The script can be continued, but with files over 8.00mb there is a
possible DoS, as the script must constantly be 'continued'.

# Request/Response pairs are stored in javascript arrays. Run this extension
for a long time any firefox may run out of memory - don't do this

Sounds like it's probably a known issue - you run long enough, those javascript
arrays are gonna get big and piggy, and trigger the "stop the script" warning.
Or can you verify that you're seeing some different issue?
