Now click I’ll be careful, I promise!

02. You will see a label there Filter, just next to it type network.http.pipelining. Now be sure the value field is set true, if not double-click to set true.

Info: HTTP is the application-layer protocol that most web pages are transferred with. In HTTP 1.1, multiple requests can be sent before any responses are received. This is known as pipelining. Pipelining reduces page loading times, but not all servers support it!

03. Go back to the Filter search bar and type network.http.pipelining.maxrequests Double-click this option and set its value to 8.

04. In the Filter search bar and type network.http.proxy.pipelining Once opened double-click on it and set it to true.

05. Type network.dns.disableIPv6 in the filter search bar and set this option to true by double clicking on it.

Info: In IPv6-capable DNS servers, an IPv4 address may be returned when an IPv6 address is requested. It is possible for Mozilla to recover from this misinformation, but a significant delay is introduced.

06. CONTENT INTERRUPT PARSING

This preference controls if the application will interrupt parsing a page to respond to UI events. It does not exist by default.

Right-click (Apple users ctrl+click) anywhere in the about:config window, select New and then Boolean from the pop-up menu. Then:

07. Rather than wait until a page has completely downloaded to display it to the user, Mozilla applications will regularly render what has been received to that point. This option controls the maximum amount of time the application will be unresponsive while rendering pages.

Right-click (Apple users ctrl+click) anywhere in the about:config window, select New and then Integer from the pop-up menu.

08. CONTENT NOTIFY INTERVAL

This option sets the minimum amount of time to wait between reflows. Right-click (Apple users ctrl+click) anywhere in the about:config window, select New and then Integer from the pop-up menu.

steps in speeding firefox

A. Type content.notify.interval in the New integer value pop-up window and click OK.

steps in speeding up firefox

B. You will be prompted to enter a value. Enter 750000 and click OK.

09. CONTENT NOTIFY ONTIMER

A. This option sets if to reflow pages at an interval any higher than that specified by content.notify.interval. Right-click (Apple users ctrl+click) anywhere in the about:config window and select New and then Boolean from the pop-up menu.

10. Notify Backoffcount

This option controls the maximum number of times the content will do timer-based reflows. After this number has been reached, the page will only reflow once it is finished downloading. Right-click (Apple users ctrl+click) anywhere in the about:config window and select New and then Integer from the pop-up menu.

steps in speeding firefox

A. Enter content.notify.backoffcount in the New integer value pop-up window and click OK.

11. CONTENT SWITCH THRESHOLD

You can interact with a loading page when content.interrupt.parsing is set to true. When a page is loading, the application has two modes: a high frequency interrupt mode and a low frequency interrupt mode. The first one interrupts the parser more frequently to allow for greater UI responsiveness during page load.

The low frequency interrupt mode interrupts the parser less frequently to allow for quicker page load. The application enters high frequency interrupt mode when you move the mouse or type on the keyboard and switch back to low frequency mode when you had no activity for a certain amount of time. This preference controls that amount of time. Right-click (Apple users ctrl+click) anywhere in the about:config window and select New and then Integer from the pop-up menu.

steps in speeding firefox

A. Enter content.switch.threshold in the New integer value pop-up window and click OK.

steps in speeding up firefox

B. You will be prompted to enter a value. Enter 750000 and click OK.

12. NGLAYOUT INITIALPAINT DELAY

Mozilla applications render web pages incrementally, they display what??™s been received of a page before the entire page has been downloaded. Since the start of a web page normally doesn’t have much useful information to display, Mozilla applications will wait a short interval before first rendering a page. This preference controls that interval. Right-click (Apple users ctrl+click) anywhere in the about:config window and select New and then Integer from the pop-up menu.

steps in speeding firefox

A. Enter nglayout.initialpaint.delay in the New integer value pop-up window and click OK.

steps in speeding up firefox

B. You will be prompted to enter a value. Enter 0 and click OK.

That’s it! Now restart Firefox and your browsing as well as downloading speed will be much more faster. Good luck.peace

    Its worked great for me,but I cant access some websites e.g: bbc news.I get a connection interrupted error.

  8. Jane says:

    The tweak reduces FF memory usage to 10Mb when minimized. It resumes full usage (about 80Mb for me) when maximized. This is useful when you're running memory intensive programs but still want FF open for downloads or whathaveyou.

    - This doesn’t increase Internet Speed, but close up some bad or missing parameter settings – If Any Noticeable Speed Increase.

    - You’ll have to tweak your computer/device parameters (example: SG TCP Optimizer 3.0.8; [my tweak set is 55Mbps > Optimal > Set all devices -- Use the highest bandwidth your modem/router reports through network connections]) or buy a better bandwidth plan or find a better ISP company (some companies just suck). Some hardwares require the latest driver update to notice any speed changes.

    - Personal Opinion: Speed Test Websites can be throttled to show higher speeds (ISP filter or whatever), so I generally don’t trust that type of test. The data is useless for personal/private use any ways (good for quick general line test, not all out internet data test) — best to test with data that you’d be using normally.

    I use (example) NetWorx 5.2.2 (it’s free) to keep track of logged Usage Statistic speeds (Settings > Usage > Graph > bits/s instead of bytes/s; most companies advertise in Mbps (MegaBitsPerSecond)).

    I use movie/video sites (Crackle) and graphic game sites (1st Person Shooters, etc.; Dead Frontier, Quake Live, etcetera) for my internet speed tests (observe NetWorx Usage Stat over time).

    Example Case (Before Using This Firefox Tweak): I’ve used over 10 different Internet Speed Test Sites which may show 2Mbps to 8Mbps DL/UL (download/upload), my Router/Modem shows 28Mbps to 54Mbps, and testing a movie load (20 minute to 2 hour video is sufficient) NetWorx showed less than 1k (0bits to 1024 bits) to 45k – 54k (dial-up speed). The movie website (Crackle) is open to much larger download speeds than this for serving 320p/480p.

    Much Thanks for this Firefox Tweak!
    - I have noticed a Faster Browser Response Time to interact with a website before it is fully loaded. Very useful when I know where I want to navigate into and don’t want to wait for anything I don’t need to load … to get to the destination point.

    - I’ve also noticed a Faster Page Refresh Time (Pipe, Parse, Paint/Display) to Website Interaction (Switch Threshold) Time.

    - Thanks for the ‘network.dns.disableIPv6 = true’ which is also a known security issue (unused open function – circumstantially exploitable) besides an extra speed delay. The reason it usually returns IPv4 is because that’s what everyone uses. Most companies have IPv6, are unaware that they have it, do not disable it, and continue to use IPv4.

    - And Holy Manure! I’m noticing a 1Mbps to 4Mbps video download rate through Crackle (8.42Mbps to 13.9Mbps max transfer rate – not utilizing for whatever reason). Video clipping and Audio sync is now good in standard view (none occurring), but I’m still getting some slowdown and miss-syncs in Full Screen 320p/480p (129 kbits/s to 580kbits/s is the reason). Obviously, my internet connection is being throttled — just observing my radical measurements all over the place.

    If you come up with any other tweaks or parameter settings [short of physically hacking my modem/router to completely open the bandwidth which would get me into legal problems :D], let me know. Thanks Again!
