Speed up Firefox
One important thing regarding with internet is browsing speed.
By default, Firefox runs fast enough. But you can amplify your browsing experience a little bit by modifying a few settings.
In the address bar type about:config and press enter. Scroll down to network.http.pipelining options. Set the value of
Network.http.pipelining.maxrequests option to 30. Firefox now send up to 30 http requests at once. (It will not be always true; but you can make your browsing little bit faster)
Firefox usually send all http requests to a server one after the other. Once it sends a request, it waits for a response before sending next request.
Set network.http.pipelining and network.http .proxy.pipelining to true.
By default Firefox takes about 250ms to render a page. Right-click anywhere on the about:config page and select New – Integer. Then type in nglayout.initialpaint.delay and enter 0 as its value. Firefox will now render pages immediately instead of waiting its default 250 ms.
