Load Time Analyzer for Firefox

By Daniel Scocco

This is a very useful Firefox extension for web developers, designers and bloggers. We all know that speed is a key component of usability, and that the loading time of your website will make the difference between people actually navigating it or just skipping it altogether.

Load Time Analyzer is a Firefox extension created by Google that displays the number of events that are processed by a certain website and how long it takes to load them all. The load time displayed will obviously be influenced by your Internet connection, nonetheless it can provide a good indicator of the site speed.

The most interesting part of this extension are the detailed graphs that it outputs for every single site. On the graphs you will be able to see what objects are creating bottlenecks, how many external requests the site has, what plugins or scripts are placing requests and so on.

Update: If you are having problems with this extension try Firebug. It also provides more functionalities.

    Seems like a great plugin, I will try it. I’m using FasterFox (http://fasterfox.mozdev.org/) for measuring page loading time.

    I also does some network tweaks and increases the page loading speed.

    Thats a cool plugin. I wouldn’t necessarily use it often but i think for someone whose trying to speed up their site connection it will be useful.

    Christian, FasterFox is another great plugin. I also use it. The Load Time analyzer is useful when you need to tweak or analyze the design of your website.

    It is a good idea to see how many events you have in comparisson to other sites on the same niche, and try to keep that number as low as possible.

    A nice plugin, but when you’re using ‘Firebug’ (a debugging/code tracking extension) you’ll also be able to see that, including parse and delay times, pretty neat and it offers way more useful functions 😉

    Holy Crap! I downloaded the plug-in and it crashed Firefox, no longer allowing it to load.

    I’m seconding “just use Firebug”. It’s amazing. One of the best Firefox extensions ever made.

    I just installed it and it crashed my Firefox too. I can’t open Firefox anymore unless I use safe mode.

  • Anthony

    Aylee,
    Just load it up in safe mode go into the Add-Ons and uninstall it. That’ll solve the problem.

  • Daniel

    Strange that an extension made by Google is crashing you guys, I guess they cant be perfect on everything :).

    I will check Firebug, I had heard about it but never played with it.

    If this was my computer I would’ve downloaded Firefox by now and used that tool! Though, I suppose if you can check sites that don’t belong to you if anyone has time they could check my site for me, but only if you want to! The blog I’m most concerned about is http://repriisent.blogspot.com

    Is it only me?
    The plugin does not work in my browser. I have v2.0.0.3. It keeps crashing when i start the browser.
    So, I ran firefox in safe mode. Disbaled the plug-in, and then my firefox started properly in normal run.

    Sounds interesting!! Will check this one for couple of sites I am optimizing for quick and faster loading.
