The Throttle Firefox extension doesn't work on linux.

Is there a utility for linux that could throttle the bandwidth usage for a particular program/process, or even the entire system?

Main usage would be for web development, to test the user experience when the connection is slow.

trickle is what you're after.

  • Not exactly what I need. I need to be able to change the limitation while firefox is running.
