Firefox

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.
