Firefox Iphone Emulator

I'm sometimes amazed by new Firefox extensions that get developed. One of those that surely has its uses is the Firefox iPhone Emulator extension which is currently an experimental build. Don't expect to control the Apple iPhone with all its features in Firefox. It currently offers the iPhone interface and the ability to navigate websites. While this does not sound like much it could provide to be very useful for webmasters.

If you ever wanted to know how your website looks like when opened from someone using an iPhone or mobile phone then this iPhone emulator will deliver that right in Firefox. No other emulator or experiments are needed to achieve this.

The display of my own website is definitely not optimal. I never gave much thought to it before but I think it is a good idea to search for solutions on how to provide users with these devices a better experience on my website.

Just install the extension as usual and start it from Tools > Launch Iphone Emulator.

Update: The Firefox extension does not seem to be available anymore. There is an alternative available on the Test iPhone website that you can make use of instead. The site is not really offering all the functionality that the iPhone has to offer though, as it seems more like a template that the websites are displayed in.

It is nevertheless ok for a quick view of how a web page or website is displayed on the phone. For real optimization it is recommended to use a real iPhone to make sure everything is working correctly.

    Take care about,

    It only displays your site with your browser width, not the iphone 4 really detected width (900px on little screen).

    You’r faster minimizing your own browser window and reload the page.

    I only found which looks like a pretty realistic emulator for iPhone / iPad, even it is based on Adobe Air with I guess Apple disagrees with.

    Good luck for your adaptative design.

    Ya know, I thought the online iphone emulators actually worked like the iphone does.

    But…. they play flash. Umm… are these nothing more than stripped down versions of your browser window in an iframe that looks like an iphone?


    USE A REAL iphone or the SDK to get the real story!

    I’m impressed with the iPhone firefox extension – I also use a simple web-based iPhone emulator which I send clients to view their site in
