Mozilla has outed its new Firefox Developer Edition 38, the first version that includes support for a 64-bit version of Microsoft Windows.

The addition of a 64-bit version for Windows users will be a boon for native game developers who want to deliver slick speeds and desktop quality experience from apps within the browser window itself.

The improved experience is possible because the recommended heap size in the older incarnation of Firefox is 512MB, whereas the 64-bit heap size can go up to 2GB.

It also brings with it faster task execution, increased security and the whole browser experience just feels that little bit faster when set against the older edition.

Hitting all PCs in May

Reports back in October 2014 claimed Mozilla was planning to bring 64-bit support with Firefox 37 originally by March 31 2015, but it will actually be hitting the release channel during the week of April 7.

Firefox 38, meanwhile, is expected to arrive to end user PCs in May after landing on the beta channel in the big April 7 week. Until then Windows users that want a slice of the 64-bit action can already take advantage of Internet Explorer, Google Chrome or Opera already running in the souped up state.

A new stable release of Firefox has been made available for download by Mozilla.

The world’s most popular piece of open source web-browsing software hits version 36 with this new release. Chances are you won’t notice the upgrade since everyone uses Google Chrome*  but let’s take a look at what’s new anyway.

New Features in Firefox 36

The big key user-facing new feature in Firefox 36 is support for syncing pinned tiles on the New Tab page across desktops. This feature fixes a bug first filed back in 2012.

Pinned tiles are kept in sync across desktops (sadly mobile versions of Firefox, including Firefox OS, are excluded) using your Firefox account. It’s a nice touch for those tired of seeing different websites on their Ubuntu laptop, their Fedora workstation, Windows PC, etc.

Firefox 36 also introduces support for the HTTP/2 protocol, which “enables a faster, more scalable, and more responsive web.” Recently adopted by Google, it’s hoped that HTTP/2 will replace the HTTP 1.1 protocol in use since 1999.

Unlike most upgrades Firefox 36 also has the potential to break compatibility with a number of popular Firefox add-ons.

As annoying as this may be it is also necessary. The changes, though minor, are designed to help Mozilla protect Firefox users from malicious or malformed extensions. Making a few tweaks to the types of things add-ons can and can’t do at the code level is a key part of doing that.

Developers will find some minor new developer options available to them, including paste options, in the Inspector markup view.

There’s also the usual smattering of bug fixes — including one that saw users logged out of Facebook after restarting Firefox — and important security updates.

Download Firefox 36 for Ubuntu

A free download for Windows, Mac and PC, Firefox can be found on the official Mozilla website. Although you’ll find some handy .deb installers of Firefox 36 here Ubuntu users don’t need to use them.

If you’re on Ubuntu 12.04, 14.04 or 14.10 (or a Linux distro based on them) you’ll receive Firefox 36 via the Software Updater tool in the next 24–48 hours. Automatically, no fuss. Pretty neat, eh?
