Chrome and Edge make it simple to ‘install’ pages, so they’re easy to pin to the task bar. PWAs for Firefox gives that capability to Firefox, but it’s a bit brittle, and breaks easily if Firefox updates. It’s broken again for me tonight and the usual ‘reinstall this reinstall that’ hasn’t fixed it.
In my opinion Firefox took a significant backwards step when they killed that feature years ago.
I appreciate I might not be the target audience for Lemmy since I’m half Windows half Unix, and a Gmail / Keep / Calendar / Facebook / Messenger user.
Firefox is currently in the process of rebuilding the official support. I don’t have particularly high hopes that they will get it right, but I’m reserving judgement until I see it.
