Firefox Browser 52 Announced With 'Game Changing' Support For Complex Web Apps

by

Mozilla has heralded the release of a new version of Firefox that it says enables resource-intensive web content like games, apps, and image-editors to run in a browser window at previously unachievable native speeds.

To accomplish the feat, Firefox 52 supports Web Assembly, a new standard developed by Mozilla, which it calls "a game changer for the web".

Web Assembly

WebAssembly allows complex apps, like games, to run faster than ever before in a web browser. We expect that WebAssembly will enable applications that have historically been too complex to run fast in browsers – like immersive 3D video games, computer-aided design, video and image editing, and scientific visualization. We also expect that developers will use WebAssembly to speed up many existing web apps.

Mozilla has posted a video, embedded below, that shows the WebAssembly standard and WebGL 2 in action, with the help of a 3D environment demo rendered in real-time using the Unreal 4 Engine.

In addition to Web Assembly, the update adds automatic detection of "captive portals" often used by hotel wifi networks that require the user to log in before they can access the web.

Mozilla has also built contextual alerts into input fields to warn users when they're prompted to enter username and password information on a page that isn't encrypted with HTTPS.

Other additions to this version of Firefox include CSS Grid, a Grid Inspector developer tool, and automatic disabling of plugins that use the Netscape Plugin API (NPAPI) besides Flash.

Firefox 52 is a free download for the Mac.

It's a good thing your personal needs dictate the development of web technologies.
.....Flash has a new critical vulnerability announced nearly weekly at this point. Web technologies have all leapfrogged past flash in capability, so other than specific in-house websites for enterprise reasons....why the hell does flash still need to be a thing? No modern website is being designed in Flash.

Looks like they finally are removing all plug in support except flash. It's time for flash to go too folks. The last computer I had flash installed on was my PPC G5.

Because some websites still rely on it. The world doesn't change the instant a new technology is developed.
"The instant".......are you familiar at all with the history of Flash? :rolleyes:

It's been nearly a decade since the world learned, through many failed attempts, that Flash is simply never going to be an acceptable technology for mobile. Thus, if you are professionally developing a new website in 2017 that is based on Flash (and is NOT an internal company page), you are simply incompetent. It really is that simple.

Note very carefully what I'm saying. I understand a website developed in 2006 and never updated relies on flash.

Yup. If you develop a site using Flash, you're doing it wrong.

Of course, developers of all stripes are notorious for being lazy as hell, and loathe learning new skills. Plenty of greybeard Windows devs still behave like they're developing for Windows 98.
