I use PWAs extensively and Firefox decided they won't bother to implement them, so that's going to be a no from me. Rather than wanting the web platform to be first class, they really want it to languish as a second-class citizen. Really sad, seeing as they also fired devs, and invested in "AI" instead.
I personally hate PWAs even the ones I use on mobile (with firefox). Not being able to open a link in a second tab for example. I much rather just open the web app in a normal browser. PWAs just seem to reduce functionality over a normal web page.
But in all fairness, it’s easier to build one poorly, and there isn’t much incentive not to.
