Setup was bit of a hassle as despite the setup page saying otherwise, it never installed 7zip for me.
So i was stuck there for a moment.
Then the addon didn't appear around the other add-ons, so i couldn't make pwa's on every page I wanted.
But later it just appeared next to ublock origin in the user interface.
From there it did make it possible for me to create pwa's from every page I wanted, so while installation was bit complicated hassle it does everything that it promises to.
So 5/5 addon in my book.

Funciona muito bem! Inclusive no Ubuntu 22.04 LTS, porém, não funciona se você estiver usando a versão Snap do Firefox.

Works excellently in installing any website as a PWA

Excellent add-on, super useful!

Awesome to have PWA back in Firefox! Thanks to the developer 💪

It's working for me. Setup is quite simple, and UI is useful and clean. Thank you for making this addon and making PWA possible for Firefox.

I really wish that Firefox would have left this feature in natively. I use it daily, thank you for making this.

Very useful extension

Amazing

This is one of the few firefox add-ons that is REALLY AWESOME and doesn't have ANY negative downsides.

Works like a charm. I can only hope FireFox gets native support one day so this isn't needed.

Great extension, works perfect and is super user friendly!

Awesome, works amazingly :D

Funciona perfeitamente, apenas precisa instalar 3 aplicativos que a própria extensão encaminha você para os links, todos os link seguros. Firefox forever S2
