The Instructions listed bellow are tips and tricks on how to optimized your surfing experience using the browser Firefox. Firefox has been outperforming IE in every department for years, and version 3 is speedier than ever. But tweak the right settings and you could make it faster still, more than doubling your speed in some situations, all for about five minutes work and for the cost of precisely nothing at all. Here's what you need to do.
1. Enable PipeliningBrowsers 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 don't 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 quicklyLarge, complex web pages can take a while to download. Firefox doesn't want to keep you waiting, so by default will display what it's received so far every 0.12 seconds (the "content notify interval"). 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 in the address bar and press [Enter], then right-click somewhere in the window and select
New > Integer. Type
content.notify.interval as your preference name and click OK, enter
500000 (that's 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 loadingIf you haven't 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 in the address bar and press [Enter], right-click in the window and select
New > Integer. Type [/b]content.switch.threshold[/b] and click OK, enter
250000 (a quarter of a second) and click OK to finish.
4. No interruptionsYou 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 in the address bar and press [Enter], right-click in the window and select
New > Boolean. Type
content.interrupt.parsing and click OK, set the value to
False and click OK.
5. Block FlashIntrusive Flash animations are everywhere, popping up over the content you actually want to read and slowing down your browsing. Fortunately there's a very easy solution. Install the
Flashblock extension [url=flashblock.mozdev.org]flashblock.mozdev.org[/url] and it'll block all Flash applets from loading, so web pages will display much more quickly. And if you discover some Flash content that isn't entirely useless, just click its placeholder to download and view the applet as normal.
6. Increase the cache sizeAs 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 in the address bar 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 TraceMonkeyTraceMonkey 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. It's still buggy so isn't available in the regular Firefox download yet, but if you're willing to risk the odd crash or two then there's 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 that's it - you're running the fastest Firefox javascript engine ever.
8. Compress dataIf you've a slow internet connection then it may feel like you'll never get Firefox to perform properly, but that's not necessarily true. Install
www.toonel.net and this clever Java applet will re-route your web traffic through its own server, compressing it at the same time, so there's 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 you're on a limited 1 GB-per-month account, and can at best double your browsing performance.
