Background

HTTP is the application-layer protocol that most web pages are transferred with. The total number of HTTP connections the application can make to a single server is limited by this preference. If more connections are needed, they are queued until a connection "slot" is available.

Possible values and their effects

This preference takes values between 1 and 255 inclusive, directly corresponding to the maximum number of HTTP connections Mozilla can have open at once. (Minimo default: 2. All others default: 8. Firefox 3: 15)

Caveats

  • If you are using a proxy, the proxy server - not the server the content is coming from - is the server affected, so this effectively limits the maximum number of total connections.
  • The maximum number of connections to all servers is controlled by network.http.max-connections.

Recommended settings

If you experience problems not being able to download multiple files from a site, you can raise this value. It is, however, considered poor etiquette to make too many connections to a server and may lead to you being banned from that server.
