Rated 4 out of 5 stars

This add-on was partly solving my problem with bad rendering in Firefox 4. But when I updated to the latest version (11.03.25.01), I was back to point zero.
I reinstalled version 11.01.11.01 and the rendering was better again!! That's why it gets 4 out of five stars.

This review is for a previous version of the add-on (11.03.25.01).
