Button’ and launches Developer Edition browser
Firefox Dev Edition has a few particularly useful features for developers, like WebIDE integration for
full in-browser editing and will allow developers to do things like remotely debug a page or Web app
running in Chrome or Safari on a tablet. Clearly, this could save a lot of time and hassle - and
removes the need to actually have a different set of developer tools for testing with each browser.
"Behind the scenes, one of our major engineering investments was to ensure that we maintained a
position of encrypting all your information before it moved into the cloud," explains Nightingale. "It
was important to us that we safeguard that. But the experience for users has been transformative.
When you talk to people who have 'sync' working between multiple devices, you talk about the
physical way they interact with it. It's so different to experience a connected and integrated
Firefox... If we project forward, we should anticipate there will be so much more of that. That most
people will have a Web expereince that isn't mediated by a single device."
While it's loosely based around the previous Firefox Aurora builds, it's not a straight-forward
rebrand - it's closer to the nightly builds, but built for a developer user base with different needs. It
also removes a lot of the safeguards that are vital in the consumer browser but that can frustrate
developers.
"We have excellent tools built into Firefox today around things like Web Audio - which is a standard
we helped write - and if we wait for some other browser developer to build tools for it, it may or may
not be a priority for them," he explained. "If we don't have a tool chain that supports that [potential
of the Web], it's not going to go anywhere and I don't want to pin my hopes there on companies
that happen to own smartphone platforms that are making a really strong argument to their
developers about why you should stay native and not build for the Web."
Of course, switching to private browsing is still an option, but now you have an extra conduit to
erase some of the recent past without having to mess about under-the-bonnet.
For its most recent release, the company simplified the Mozilla sign-in process, and made it easier to
find.

2. Native or Web apps is an argument that's not likely to go away any time soon, but with a whole
new developer browser and some crowd-pleasing consumer features, Firefox is doing the best it
can to ensure that it stays relevant and popular for the next 10 years.
"For a long time, Firefox didn't ship any developer tools because the best developer tool out there
was an add-on for Firefox called Firebug," Nightingale said. "Obviously, over time other browser
vendors started investing a great deal in developer tools and it became clear to me that this was an
area we needed to be invested in, not just to be competitive in terms of the hearts and minds of
those developers but also because we have opinions about some other stuff."
Why now?
It has also included a new walkthrough to highlight some of the new privacy features for the exact
same reason - there's not much point introducing new tools for people if no one uses them. Android,
too, is getting a privacy coach.
By opinions, Nightingale means that the company has thoughts on Web standards and privacy that
might not be priorities for other browser vendors whose futures currently look more heavily invested
in native apps.
The consumer-facing browser is also getting an oft-requested 'Forget Button', which is essentially a
retrospective 'porn mode' option. Using it allows you to clear between 5 minutes and 24 hours of
browser data - history, cookies, log-ins, saved passwords etc. - but it leaves the rest of your stored
data and auto-complete history in place. It also closes any browser windows you have open and
presents you with a fresh, blank one.
Now, according to Firefox VP Johnathan Nightingale, the killer feature for a Web browser is ubiquity
and feature-parity across different platforms. With the number of devices-per-person rising globally,
it's not hard to see why this would be so important. But this isn't without it's challenges.

3. Of course, in 10 years the Web has changed significantly. In 2004, Firefox made its name by
introducing smart pop-up blocking - and cemented it by popularizing tabbed browsing, even if it
wasn't the first to offer the option.

Developer browser
The visual appearance of the Dev Edition is very sparse and has taken the previous dark-themed dev
tools and applied it to the whole browser. Layout-wise, having a standalone developer browser
allows Mozilla to promote tools front-and-center, rather than buried away in a series of sub-menus.
Among other changes to the browser, Nightingale said, is the addition of DuckDuckGo as a standard
search option, alongside Google, Yahoo and the rest of the list of providers.
With Firefox having existed for a decade, Nightingale said that part of its decision to launch the

4. standalone developer browser now was driven by its competitors' development tools. There's
definitely an element of 'keeping up with the Joneses', but it's more than that.
Today, Mozilla's Firefox turns 10 years old, and to celebrate the occasion, the company announced
a handful of new features for its main consumer-focused browser - and shared more information
about the Developer Edition browser, first revealed last week.
