Extend PWA support to Linux and MacOS

[VTuberLoreSimp]

Progressive Web Apps have been supported on Firefox since version 143... But only on Windows (not to mention only when installing Firefox outside the Microsoft Store).

I'm surprised that they haven't been brought over to Linux (and MacOS) yet! Regardless of the actual barriers, I wish and hope for them to be supported pronto!

Thanks for submitting an idea to the Mozilla Connect community! Your idea is now open to votes (aka kudos) and comments.

This has recently been shared in the main PWA request thread - Bring back PWA (progressive web apps) - so I'll add it here too: support for Linux is being worked on right now and could land in Firefox as early as version 149.

Hi, please add the support of the PWA on MacOS to let us use Firefox only.

Having PWA in Linux distros (specially the .deb) would make the Firefox my only installed browser in Kubuntu. I've been wanting this feature for a while, my dad just moved to Zorin OS and he's waiting for this feature either.

Firefox on macOS not having Taskbar Tabs/Progressive Web Apps is shocking to me, i am on Firefox 152 and it wasn't on Planned Feature list Firefox released, i hope it comes to macOS soon
