A new version of Firefox released today puts some extra speed into online games and Web apps powered by JavaScript, thanks to a new compiler called IonMonkey.

Mozilla stated in a blog post announcing the update to Firefox 18 (download for Windows | Mac | Linux) that the new engine makes JavaScript-powered Web sites run up to 25 percent faster than before.

Firefox will now look better on Macs thanks to new Retina support, and all versions of the browser work with W3C touch screen events in addition to MozTouch events.

LAS VEGAS--As Firefox OS develops partially in the public eye, Mozilla shows off two interesting changes to how the operating system handles apps at the CES 2013.

The first change could have wide-reaching consequences for anybody who's built a Web site and wants to get in on the mobile app revolution. Part of the Everything.me investment, Mozilla has come up with a way for people to turn their Web sites into mobile apps using manifest files. It could revolutionize app marketplaces, said Christian Heilmann, Mozilla's lead developer on Firefox OS.

"App markets right now are like … Read more

Firefox for Android can request desktop versions of sites, but you have to make the request every time you visit a site that loads a mobile version. You can use Firefox add-ons to change the browser user agent string, but if you don't want to install add-ons, you can make the change directly to Firefox. Here's how:

Step 1: In the Firefox address bar, type "about:config" and press Enter.

Step 2: Tap the "Add a New Setting" button, then select "String" as the type.

Step 3: For name, enter "general.… Read more

commentary Would you ever consider buying a smartphone running Ubuntu, Tizen, or Firefox as its operating system? For most of you, the answer is and will probably remain: No.

Why would you? Android and iOS fight for worldwide domination, with no signs of slowing down. Both have extremely well-developed ecosystems that make sharing information across services and even across individual handsets a fairly simple, unified process. App development is strong, and OS updates are regular enough to give phone owners new party tricks to show off.

In the meantime, Microsoft is still reaching deep into its pockets to secure double-digit … Read more

Big changes to Firefox's "porn mode" -- the private-browsing feature that turns off recording cookies, history, and temporary files -- landed today in the Firefox Nightly build.

When it reaches the general public a few months from now in Firefox stable, the feature will allow you to run the private-browsing feature in a new window, without closing your regular instance of Firefox. This pulls the browser up to parity with Chrome, Internet Explorer, and Opera. Safari doesn't open private browsing into a separate window.

Firefox's project manager, Asa Dotzler, stated in the blog post announcing … Read more

SAN FRANCISCO -- Microsoft's not the only big tech player taking a gamble on a new direction. Mozilla made an aggressive argument for Firefox OS to Web and app developers Monday night at its confusingly named Mobile Monday Mixer -- confusing because the company held the event last night at its San Francisco office.

As the lights from the Bay Bridge blinked in the background, Jay Sullivan, Mozilla's vice president of products, laid out why developers should care about Firefox OS. "If you're looking to build and develop mobile software without the 30 percent toll [Apple … Read more

Adobe decided to kill off support for its Flash Player on Android a while back. Unfortunately, that didn't mean all Web sites you visit would start using HTML5 instead of Flash (though it would have been nice). So what can you do if some of the Web sites you want to look at are using Flash and your new Android device doesn't have support for it?

Fortunately, the last version of Adobe Flash Player that landed on the Google Play Store will work with your Jelly Bean device. However, since it's no longer available through the Play … Read more

A JavaScript engine called IonMonkey, Mac Retina compatibility, and better touch support move into the new Firefox Beta, released today.

Firefox 18 Beta (download for Windows, Mac, and Linux) arrives with a new "just-in-time" JavaScript compiler called "IonMonkey" for faster site load times. While it doesn't appear to have been independently tested yet, Mozilla's own IonMonkey benchmarks from September indicate that it will make the stable version of Firefox 18 about 25 percent faster than the current Firefox 17. The features are expected to reach the Firefox stable channel around the first week of January. … Read more

Mozilla engineering manager Benjamin Smedberg has asked developers to stop nightly builds for Firefox versions optimized to run on 64-bit versions of Windows.

A developer thread posted on the Google Groups mozilla.dev.planning discussion board, titled "Turning off win64 builds" by Smedberg proposed the move.

Claiming that 64-bit Firefox is a "constant source of misunderstanding and frustration," the engineer wrote that the builds often crash, many plugins are not available in 64-bit versions, and hangs are more common due to a lack of coding which causes plugins to function incorrectly. In addition, Smedberg argues that … Read more
