Rated 5 out of 5 stars

Great add-on! It's the best zoom available for firefox, but there are some graphical bugs using firefox 14.0.1 with large icons (-/+ buttons disappear) or using dark backgrounds (black writing isn't easily readable)

This review is for a previous version of the add-on (4.2.1-signed). 

Fixed in Version 4.3

These problems are fixed in Zoom Page 4.3. The +/- toolbar buttons are now correctly displayed when using Firefox 14.0.1 with large icons. Dark themes are now correctly detected and the icons for the +/- buttons are changed accordingly. Note, themes with dark backgrounds should change the default font color so it is easily visible.
