How to limit download traffic in Firefox

Question

Is there a setting in Firefox to limit the download traffic speed? For example, I want to download some files using Firefox with max. 200 kbps whereas I want to use the remaining limit to download some other files with a torrent client.

Note: I don't like to use an external download manager. I'd prefer a Firefox add-on instead.

Answer 1

The Firefox Throttle add-on might help you out.

Features

• Limit download and upload rates for all open Firefox windows/tabs and downloads
• Bursting mode (allow short rate "bursting" after inactivity)
• Preset and custom limits
• Configurable lists for IP addresses and domains that should be throttled or excluded from throttling
• Automatically excluded LAN IPs
• Throttle localhost connections (New!)
• Traffic stats (for current session and historic since last reset)
• Status panel with current bandwidth utilization indicators (or traffic counters)
• Quick throttling on/off toggle on status panel

It's experimental though.

Answer 2

You can also use netlimiter. It is a shareware tool where you can adjust how applications use your internet connection.
