The loss of built-in PWA support was the biggest disappointment I had when switching from Chrome to Firefox, with the add-on solutions I tried having one problem or another in replicating my goal of making opening a handful of websites I had set to be PWAs look as much like regular applications as possible. While I wouldn’t switch back to Chrome in a second, and am still trying to get the rest of my family to make the switch, there’s a number of things Firefox needs to implement to remove the remaining roadblocks for people looking to make the switch away from Chrome or another Chromium browser.
