Anecdotally (not to diminish any bug the parent had), SingleFile is one of my favorite extensions. Been using it for years and it's saved my ass multiple times. Thank you!

Edit: What's the best way to support the project? I'm seeing there's an option through the Mozilla store and through GitHub. Is there's a preference?

Thank you also for the kind words! Regardoing support, you can choose whichever method you prefer; it makes no difference to me actually.
