8 New FIREFOX V3 Hacks to make Firefox go extreme fast

Post by Streetz on Sat Dec 13, 2008 3:11 am

The Mozilla FireFox V3 is undoubtable a great browser , but with some little Hacking tweaks ,u can doublize its performance..


1. Enable pipelining

Browsers are normally very polite, sending a request to a server then waiting for a response before continuing. Pipelining is a more aggressive technique that lets them send multiple requests before any responses are received, often reducing page download times. To enable it, type about:config in the address bar, double-click network.http.pipelining and network.http.proxy.pipelining so their values are set to true, then double-click network.http.pipelining.maxrequests and set this to 8.

Keep in mind that some servers donít support pipelining, though, and if you regularly visit a lot of these then the tweak can actually reduce performance. Set network.http.pipelining and network.http.proxy.pipelining to false again if you have any problems.


2. Render quickly

Large, complex web pages can take a while to download. Firefox doesnít want to keep you waiting, so by default will display what itís received so far every 0.12 seconds (the ďcontent notify intervalĒ). While this helps the browser feel snappy, frequent redraws increase the total page load time, so a longer content notify interval will improve performance.

Type about:config and press [Enter], then right-click (Apple users ctrl-click) somewhere in the window and select New > Integer. Type content.notify.interval as your preference name, click OK, enter 500000 (thatís five hundred thousand, not fifty thousand) and click OK again.

Right-click again in the window and select New > Boolean. This time create a value called content.notify.ontimer and set it to True to finish the job.


3. Faster loading


If you havenít moved your mouse or touched the keyboard for 0.75 seconds (the content switch threshold) then Firefox enters a low frequency interrupt mode, which means its interface becomes less responsive but your page loads more quickly. Reducing the content switch threshold can improve performance, then, and it only takes a moment.

Type about:config and press [Enter], right-click in the window and select New > Integer. Type content.switch.threshold, click OK, enter 250000 (a quarter of a second) and click OK to finish.


4. No interruptions


You can take the last step even further by telling Firefox to ignore user interface events altogether until the current page has been downloaded. This is a little drastic as Firefox could remain unresponsive for quite some time, but try this and see how it works for you.

Type about:config, press [Enter], right-click in the window and select New > Boolean. Type content.interrupt.parsing, click OK, set the value to False and click OK.


5. Block Flash

Intrusive Flash Animations are everywhere, popping up over the content you actually want to read and slowing down your browsing. Fortunately thereís a very easy solution. Install the Flashblock extension (flashblock.mozdev.org) and itíll block all Flash applets from loading, so web pages will display much more quickly. And if you discover some Flash content that isnít entirely useless, just click its placeholder to download and view the applet as normal.


6. Increase the cache size

As you browse the web so Firefox stores site images and scripts in a local memory cache, where they can be speedily retrieved if you revisit the same page. If you have plenty of RAM (2 GB of more), leave Firefox running all the time and regularly return to pages then you can improve performance by increasing this cache size. Type about:config and press [Enter], then right-click anywhere in the window and select New > Integer. Type browser.cache.memory.capacity, click OK, enter 65536 and click OK, then restart your browser to get the new, larger cache.


7. Enable TraceMonkey

TraceMonkey is a new Firefox feature that converts slow Javascript into super-speedy x86 code, and so lets it run some functions anything up to 20 times faster than the current version. Itís still buggy so isnít available in the regular Firefox download yet, but if youíre willing to risk the odd crash or two then thereís an easy way to try it out.

Install the latest nightly build (ftp://ftp.mozilla.org/pub/firefox/nightly/latest-trunk/), launch it, type about:config in the address bar and press Enter. Type JIT in the filter box, then double-click javascript.options.jit.chrome and javascript.options.jit.content to change their values to true, and thatís it - youíre running the fastest Firefox Javascript engine ever.


8. Compress data

If youíve a slow internet connection then it may feel like youíll never get Firefox to perform properly, but thatís not necessarily true. Install toonel.net (toonel.net) and this clever Java applet will re-route your web traffic through its own server, compressing it at the same time, so thereís much less to download. And it can even compress JPEGs by allowing you to reduce their quality. This all helps to cut your data transfer, useful if youíre on a limited 1 GB-per-month account, and can at best double your browsing performance.
