If you are a big fan of Firefox you must have heard that Firefox was the best browser until recently, At present Google chrome has taken over it, and main reason for that was speed of Google chrome and security features offered by Chrome. But recently Firefox has released many version within a short period of time, most of these upgrades were not only bug fixes but speed improvement and Security enhancements. In A earlier post we shown you How to Speed up Firefox Startup, here we will show how to increase response time while loading pages.
Firefox About Config warning
If you still like Firefox and worried about speed of the browser the good news is that you can further tweak the browser for speed. here we will discuss some of the special hidden tweaks, which are not available to other normal users. These tweak will not only increase the speed of Firefox overall but also improve page load time for Firefox latest version.
Firefox has a hidden advanced menu which can be activated by typing about:config in address bar. Once you type this command, it presents you a nice little humorous warning with heading “This might void your warranty”, Click on the button “I’ll be careful, I promise!” and you are in. Now once you click that button you will see thousands of option with default values. Had you ever though that this nice Firefox browser will have so many options ? 
Anyway we will change some of the selected option to speed up Firefox further. Here is the list of options which we are going to change.
1. Send Multiple requests to a server
Firefox About Config - Network http Options
This option is defined by value network.http.pipelining, by default it is set to False, once you set it to true, it will start sending multiple simultaneous request to web server while loading the page. It improves page load time for your website. simply double click on it and it will toggle from False to True
2. Increase Number of Request to Server
Second option to look for is network.http.pipelining.maxrequests. This defines number of request to be sent, by default the value is set to 4, you can increase it to 8 or 10 depending upon your Line speed.
3. Disable prefetching of Contents
Look for option network.prefetch-next , this is usually set to True by default. Double click it and toggle it to false. This will now stop loading content of WebPages which you have not visited yet. Prefetching start loading other pages of same site which are not yet visited by you but likely to be visited.
4. Stops image placeholders display
look out for option browser.display.show_image_placeholders and set it to false. This option defines how images are displayed while they are not fully downloaded. In Google chrome you will see that the images or placeholder of image is not displayed until they are fully downloaded. However it loads all text so that you can read through the content if any. This increase page load time and you can read through the page while image is being downloaded in background.
These option should increase your page load time in Firefox by a big margin. You will be able to see a big difference after setting these options and I am sure you will love your favorite browser even more like I do.
