How to Enable Pipelining in Firefox

by Contributor

Mozilla is on the cutting edge of Web browsing and 'ups the ante' with improved browser technology every time a new version of their browser, Firefox, is released. Along these same lines is a concept called pipelining, which has to do with improving the performance of page loading. If you enable this feature, it can help diminish the wait time for loading a page.

Prepare for Pipelining in Firefox

Launch Firefox. Type 'about:config' into the address bar and then hit enter.

Watch for a list of preferences to populate the browser window. At the top of the window, there should be a search bar labeled Filter.

Double-click on the preference you want to change. Changing certain preferences may require restarting Firefox.

Enable Pipelining in Firefox

Change network.http.pipelining to True in order for pipelining to be enabled. Right-click the Status indicator (default), and select Toggle. Your Status should now read 'user set' and the Value indicated should be True.

Make sure network.http.proxy.pipelining is set to True. This will ensure the proxy server is enabled for pipelining.

Set the number of pipelining requests to 8 by double-clicking on network.http.pipelining.maxrequests. Eight is the maximum number of pipelining requests currently available.
