Hi,
I am working on a prioritized fetching of resources in a web page by 
reordering the network request generated during web page parsing. I know 
how to stop a network request in FF add-on.
Could anyone  point out the APIs that I can use in a FF add-on to either 
delay any network request or re-initiate cancel HTTP requests.

Thanks,
Kailas
