Rated 4 out of 5 stars

I just switched from opera and one of things i miss in FF is the plug-in like yours. But unfortunately it doesn't support such russian image sites like Yandex.ru, Rambler.ru, Mail.ru and many many others. Could you please add them or redesign the plug-in engine to make it more universal? Thanks.

This review is for a previous version of the add-on (1.5.8.1-signed). 

The new beta version 1.6.0beta3 supports Yandex.ru and Yandex.com image search (when you enable the Others and Google Images checkboxes). 1.6.0beta3 is available in the Development Channel area of the add-on's page.
