Other browsers "occasionally" find a way to create a PWA install.

YMMV, it never lasts.

Right now Firefox cant, at least not on any of my android phones.

Firefox uses a widget to make it work.

I've never had an issue with it, and have been using it for years. I use it for X (Twitter) so that I can avoid ads.

Looks like support for installing a PWA on Android was added in Firefox 58 back in 2018:

AS I said, YMMV. PWA install has seen many a regression. Last Android release it didn't work for me, this one it does. I presume a lot of it is due to ecosystem variations and API changes.
