Rated 5 out of 5 stars

To make this addon work in v9, simply unzip (yes .xpi files are zip files) into a folder, modify install.rdf to have <em:maxVersion>9.*</em:maxVersion>. Then re-zip that folder, and rename back to .xpi.. Install, works fine, But, as normal, remember, its not been beta, alpha, tested on v9, so if it breaks, its your fault!!!

Otherwise, it works for me, and great,, next a higher-res monitor!

This review is for a previous version of the add-on (0.4.1).
