faster networking?  

can you tell me I can change this setting, because I still new using firefox?.

type in about: config on the large search box on top of firefox, and press enter. a giant this might void your warranty warning will come up, proceed - and you will be met with a ton of options. to simply make firefox faster type in network. next to max connections per server - you must change these settings as well as max requests per server and your firefox will fly on the internet. you better research what to put into these settings first, or you could destroy your webbrowser. also checkout speedguide.net home of the tcp optimizer- they have several programs on there that will increase web browsing speed. don't install the tcp optimizer if you have a highspeed connection or your firefox might get even worse. a good program on there is a webtweak to pull down webpages faster. I use this and another program I found on that site and my firefox mostly goes super fast. hope this helps.

Ok here is the guide. (NOTE: DON’T TYPE THE BRACKETS.)
1.In the address/location bar type about:config
2.In the Filter bar type [network.http.pipelining]. Then, double-click on this line under Preference Name in order to change the value from false to true
3.In the Filter bar type [network.http.pipelining.maxrequests]. Then, double-click on this line under Preference Name and change the value from 4 to a higher number anywhere from 10 to 30. I set mine to 30
4.In the Filter bar type [network.http.proxy.pipelining]. Then, double-click on this line under Preference Name in order to change the value from false to
5.In the Filter bar type [network.dns.disableIPv6]. Then, double-click on this line under Preference Name in order to change the value from false to true
6.In the Filter bar type [plugin.expose_full_path]. Then, double-click on this line under Preference Name in order to change the value from false to true.
7.In the Filter bar type [network.protocol-handler.external.ms-help]. Now, you are going to create a new Preference Name with an Integer Value. To do this, right-click on this line under Preference Name and select New, then Integer.
7.a In the New Integer value box type in [nglayout.initialpaint.delay] and click OK. Then in the Enter Integer value box type [0] (that’s a zero) and click OK.
8.in the Filter bar again type [network.protocol-handler.external.ms-help]. Now, you are going to create another new Preference Name with an Integer Value. To do this, right-click on this line under Preference Name and select New, then Integer. In the New Integer value box type in [content.notify.backoffcount] and click OK. Then in the Enter Integer value box type [5] and click OK
9.In the Filter bar again type [network.protocol-handler.external.ms-help]. Now, you are going to create another new Preference Name with an Integer Value. To do this, right-click on this line under Preference Name and select New, then Integer. In the New Integer value box type in [ui.submenuDelay] and click OK. Then in the Enter Integer value box type [0] (that’s a zero) and click OK.

Then close your browser and restart your browser. that's it to tweak your firefox,

thank you I try this now

you can also change the max connections to 45 and the max connections per server to 30 that will also help increase your firefox speed.
