8 Tweak to make Firefox Faster

Firefox has been outperforming IE in every department for years, and version 3 is speedier than ever.

But tweaking Firefox with 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 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 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 quickly

Large, 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 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 (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 loading

If 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 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 there’s a very easy solution. Install the Flashblock extension (flashblock.mozdev.org) 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 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. 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 data

If 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 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 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.



How to make an old Firefox Add-ons Work

Just like software development process, Firefox always make an improvement by releasing new version. This is great for us. An improvement sure will make a Firefox better. But sometimes, new version release will be trouble for us. Especially if we working with Firefox Add-ons.  Sometime (and always) Add-ons developer late to make a new compatible release, thus the old one can’t run because of incompatibility.

To get along with this, install Mr Tech Toolkit. But, the latest version of this does not work with FF5. To make it work (and make your other add-ons work), follow this step:

  • Download (don’t install), v6.0.4.9000 here.
  • Next, open this file with 7zip (get that here.)
  • Once you have 7zip installed, right-click on the toolkit.xpi file, choose 7zip and Open Archive.
  • Extract the install.rdf file.
  • Open it with Notepad. Look for 2 locations of

and replace these with
This will force this add-on to be compatible with all FF versions up to just before 8.

  • Save this file and close it.
  • Now, drag it into the 7zip window, archiving it and overwriting the original file in the archive.

To make sure you did things correctly, double-click on the install.rdf file and check to make sure the maxVersion>4.* has been changed to maxVersion>7.*

Once you’ve successfully changed this, open Firefox.
Open Firefox Add-ons (orange button at top left, then Add Ons, or, compact Menu button, tools, add-ons, or Tools, Add-ons)

At the top right beside the search field, there is a button with a down arrow on the side of it. Click on this and choose Install Add on from file.

  • Then, navigate to the file toolkit.xpi.
  • Install it.
  • Restart Firefox
  • Close Firefox again
  • Open it again.
  • The problems should be solved. (You might need to close and open Firefox one more time.)

Note, if the Firefox Add-ons manager page can’t be closed, press Alt+F4 to close it.


Image Block, Blocking Image with Firefox Add-ons

Image Block, Blocking Image with Firefox Add-ons

Image Block add a toggle button that conditionally blocks / allows loading of images on Web pages. The switch button is added to the navigation toolbar (right) by default. Blocking images faster browsing results, useful in handheld devices or slower connections like GSM / GPRS / EDGE dial-up, etc.

Recently in a review of a user (thanks dellvin) indicates that the Image Block very useful when you visit a site that shows dirty and adult advertisements, while also containing useful information. If you’re not sure what you see on a webpage, just block images to avoid possible embarrassment.

It can also be used at work where your boss doesn’t allow you to surf the web or social networking websites!! They look very different (hard to see which site you are viewing) with image blocking on.

– Version 2.1 fixes a couple of bugs, adds tooltip and french language ( thanks to Vincent Caron for this update).
– Version 2.0 fixes compatibility issues with Firefox 3.5, it also adds the button to the navigation toolbar by default.

Very simple image blocking extension, hopefully useful!

Note: Unfortunately this add-ons can’t block image with selective sites
