This functionality ought to be built in to the browser.

I can't figure out why Firefox doesn't support PWA！

"Progressive Web Apps for Firefox" is a remarkable extension that truly enhances the Firefox browsing experience. It ingeniously integrates Progressive Web Apps (PWAs) into Firefox, allowing users to install, manage, and use these apps seamlessly. The extension provides a native app-like experience for web applications, which is a significant enhancement for Firefox. Its ease of use, with simple installation and management of PWAs, makes it an invaluable tool for enhancing productivity and browsing efficiency. A must-have for any Firefox user looking to streamline their web app usage! Should actually just be part of Firefox standard.

TYSM!!! I didn't want to switch to another browser to use PWA apps.

It does what it says! THANK YOUU!!! It asks for a lot of things when you install it, but then all ok -- only 4 stars because I personally prefer to "detach" the tabs, instead of going all over everything everytime... case: having my social media profile running, my firefox has all the extensions that I need/want, and I install the social media as a PWA... but then I have to do all over again as in the PWA there's a new profile, so no session, no extensions, nothing... I think this is the intention, but would be nice to have an option "use the base firefox profile instead of a new one"

DO NOT DOWNLOAD. THIS EXTENSION CONTAINS MALWARE.

The UX and install isn't the prettiest but I'm not sure if this is really fixable as an addon. At the end of the day it's fairly straight forward and works great. Thank you!

Useful for detach frequently used web apps from your daily browsing stuff, plus helps to mitigate the lack of some official apps on OS like Linux.

Looking for more control over your web apps? This PWA extension delivers. It effortlessly installs dedicated apps for compatible sites, and even lets you roll your own for others. Ditch the browser tabs and create a streamlined app ecosystem.

Sure, Chrome's built-in PWAs might be a touch smoother, but this extension compensates with customization power. Name your PWAs, slap on custom icons, and tweak their behavior to your liking. Plus, you can add extensions just for specific PWAs, like a password manager for your online shopping app.

Bonus tip: I like pairing this extension with RBTray for notification-heavy apps like Google Messages. Minimized to the tray, they stay accessible but keep your taskbar tidy.

For web tinkerers who appreciate granular control, this extension is worth a shot. It might require a bit more setup than Chrome, but the personalization options make it a rewarding choice. Give it a whirl – you might just discover your new favorite tool!

Working as intended

nice extension!

Hey Mozilla! Please add this to Firefox as default, Kudos to the Dev

La pagina de instalacion te guia paso a paso y las paginas instaladas funcionan a la PER FEC CION

works stable and fine!

Because ice-ssb is abandoned on Linux, I searched for alternatives and I found it! This extension works and it feels much better and modern then ice-ssb ever was.
Installation was maybe more complicated then any other add-on, but it was very well guided, so the whole process went without problem.
A very nice suprise is the access to Firefox extensions, settings, about:confing and others from the titlebar. I have never saw a titlebar in Plasma KDE with menus and additional elements! This rocks!

Works great, no more trouble trying command line shenanigans
