I’ve used this extension successfully on Win10 to install PWAs, most recently Elk for Mastodon: https://addons.mozilla.org/en-US/firefox/addon/pwas-for-firefox/

Yep, happily testing out Liftoff on iOS. I still find myself using Memmy more often but it’s close. Pretty nice to have a bunch of options to explore developing at such a high rate.

Fortunately I don’t think you’ll have to wait too long. I’ve been using Memmy in Test Flight since really early builds and it’s extremely impressive how mature and feature rich this app has gotten.

It’s close to being fully reviewed and approved for the App Store.
