Rated 5 out of 5 stars

I had to force compatibility to install in the Nightly build of Firefox 9 but it has not crashed yet!
I love this zoom feature and wish it was part of the build.
Nightly users that wish to use this need to have the 'Tester tools' add-on to force the install.

This review is for a previous version of the add-on (0.4.6.1-signed.1-signed).
