Firefox but dropped progressive app support In theory, I would love to use Mozilla Firefox as
my everyday web browser.
Unfortunately, Firefox is missing one key feature found in Google Chrome and Microsoft Edge,
and that’s the ability to install websites as desktop apps. Over the last year, this feature has fundamentally changed the way I work by reducing browser tab clutter and providing
faster access to favorite sites, and I can’t go back to Firefox without it.
So I was surprised to see recently that Mozilla has abandoned work on a similar feature for
Firefox. Although Mozilla once championed the idea of web apps—and, to be fair, still supports them in its Android browser—it no longer has a path to enabling them on desktop computers.
That puts Firefox at a disadvantage against Chrome and Edge, both of which are speeding
ahead in making web apps an integral part of their desktop browsers. But it’s also just disappointing to see Mozilla abandon what is becoming a bastion against walled garden
app stores.
A PATH TO BETTER WEB APPS
To get a bit technical for a moment, the specific feature that Mozilla abandoned is called “site-specific browsers,” or SSBs. These allowed websites to run in their own windows, without
address bars, navigation buttons, or other clutter. In Chrome, a similar feature is available by clicking the “…” menu, then heading to More Tools > Create Shortcut and selecting “Open as Window.” Microsoft Edge makes the feature even easier to reach: Under its “…” menu, there’s
a menu called “Apps,” with an option to “Install this site as an app.”

Still, Firefox’s SSBs were an important precursor to another technology called Progressive
Web Apps, or PWAs, which let websites behave even more what you’d find in an app store.
PWAs can store images and other assets locally so they load faster, and apps that don’t require
data from the internet can run entirely offline. PWAs can also launch when users click an
associated file type on their computers, keep the screen awake for things like presentations,
and interact with a wider range of controllers and peripherals compared to standard websites.
Just as importantly, Progressive Web Apps are easier to find and install. Both Chrome and
Edge show a “+” button in their address bars for sites that offer one of these apps, and the
sites themselves can create pop-ups encouraging users to install their web apps. Once
installed, PWAs can be uninstalled just liek a desktop app, for instance through the “Add or Remove Programs” menu in Windows.
“The signal I hope we are sending is that PWA support is not coming to desktop Firefox anytime soon,” Firefox architect Dave Townsend wrote in Mozilla’s bug tracking forums at the end of December.
Meanwhile, Apple’s Safari browser has not been particularly welcoming to Progressive Web
Apps either. Although users can “install” web apps to their home screens on iOS, the same
feature isn’t available in Safari for Mac, and Apple has refused to support a wide range of web technologies for what it says are privacy reasons. In the long run, this may be more damaging
to the state of Progressive Web Apps than Mozilla’s decision, though it’s also less surprising
given everything that Apple had riding on the success of native iOS apps.
USAGE ON THE RISE
Alex Russell, a senior staff software engineer at Google and one of the biggest purveyors of Progressive Web Apps, says he’s sad to see Mozilla abandon some of the groundwork it had
laid for PWA support.
“I understand the instinct to say, if you can’t do a really great job, then maybe don’t try,” he
says. “We have a long list of scars from having to do it ourselves.”
FROM A USER PERSPECTIVE, YOU JUST WANT THESE THINGS TO FEEL LIKE APPS.”
Russell notes that implementing Progressive Web Apps can be difficult for browser makers,
Developers say they’re seeing a payoff from Progressive Web Apps as well. The web-based
video editor ClipChamp says installation of its web app grew by 97% per month since
launching last May, and user retention rates are 9% higher compared to ClipChamp’s
desktop software.
Bil Bryant, CEO of the online music creation tool Amped Studio, says it’s too early to share
usage numbers for its Progressive Web App, which just launched about a month ago. Still,
he says it should be a popular with Amped’s users, many of whom use Chromebooks and
other low-power computers that can’t run full-blown digital audio workstation software.
AN ANSWER TO WALLED GARDENS
For some app makers, the appeal of Progressive Web Apps isn’t just about the features they
offer, but about their ability to circumvent app stores as a means of distribution.
“As a developer, you spend so much time and money creating this thing,” says Bil Bryant of
Amped Studio. “A web app is giving you the freedom to do what you want to do, and not have
to pay the Apple developer fee, and hope and pray it goes through after spending all your time developing it.”

Russell says “it’s handy for Google and Stadia team” that web apps have advanced to the
point of supporting features such as more responsive gamepad support, though he notes that Stadia’s competitors benefit from those developments as well.
While closed platforms tend to be more of an issue on smartphones, even desktop platforms
are starting to look more like walled gardens. Apple’s M1-powered Macs, for instance, can
now run iOS apps, which could further discourage development outside the App Store, and
as a Windows user, I get my fair share of scary warnings while trying to install software from outside the Microsoft Store. Progressive Web Apps are, in some sense, a great equalizer,
providing increasingly-powerful software that runs on practically any computer, no app store required.
