Firefox 4 for Mobile: Demos!

The Release Candidate for Firefox 4 for mobile (Maemo and Android) is out. If you want to see a quick overview of Firefox for Mobile, look at Madhava’s post.

Firefox 4 Desktop, Firefox 4 Mobile: same engine!

And this is awesome! It means you will find the same feature in mobile and desktop: HTML5, CSS3 and modern JavaScript APIs. And this is what we want to show you in our new round of demos in Web O Wonder (This new round also includes more 3D Demos, see this dedicated blog post).

Meet 3 new demos:

    I’m not sure where to report bugs on this, but I see two problems on my Galaxy S:
    * the canvas2d demo fills the error console with warnings about how fillStyle is being set to something that’s not a color or number
    * the webgl demo doesn’t work at all and throws an error in the console

    if (typeof vid.loop == ‘boolean’) vid.loop = true;
    vid.addEventListener(‘ended’, function()
    this.currentTime = 0;;
    }, false);
    } (shortest clip I could find in that directory)

    Oh, and if you want to ever halt that looping with removeEventListener presumably would not use an anonymous function.

    Thanks for the video. FYI this BETA only runs on ANDROID device running the ARMv7 processor. Which is a damn shame because that means only 20 devices are currently supported. Again a shame for us that don’t have a supported device.

    The lesson here is, just because an app says ANDROID supported, doesn’t mean you’re device will be supported even if you are running the latest version of ANDROID. FYI I’m running Froyo.

      Its a shame indeed, they falsely advertise that they support the Androids but they only support ARMv7 while 90% of the phones are on ARMv6. If mozilla wont bother i will just wait for Maxthon 3 for android whose beta app seemed pretty good.

        And if they wont bother supporting ARMv6 at least prepare a Firefox Home or Firefox sync for our phones, so we can at least sync our phones with our desktops, cause right now they pretty much losing from google with score being at least 2-0

          I agree totally Varamenos.

          At least there are great web browsers for ANDROID, I use Miren. And if you use Dropbox (2GB for free) you can at least get bookmarks to ANDROID without any pain.

          And the Fox2Phone Firefox add-on lets you send links straight to your phone, the first time I used this feature I had to giggle like a little school girl because it is so darn cool. Google Map directions sent to you phone will open the route for you in Google Maps. Phone numbers sent will automagically open the dialer with number ready to go.

          I believe iOS cannot do this, please correct me if I’m wrong.

          For the adventurous types out there with ARMv6, here are some unofficial alpha-builds of Firefox you can try:
