The Firefox release

Use Firefox developer edition and load an extension from a file. First disable extension signing so it works.

Now with improved reliability from scrolling

Download the "source code" zip file if you are trying to install the extension.

Now with PNG support

Allow PNG files to substitute for SVG files

Not every score has svg files available, so in that case, png files are used instead as a backup now

First version
