Rated 5 out of 5 stars

The only thing I'm missing is an option to remove all EXIF data. Could that be implemented in future versions?

This review is for a previous version of the add-on (0.15.2). 

Hi,
This "feature" is already "done": please see https://addons.mozilla.org/firefox/addon/auto-resize-image/versions/?page=1#version-0.15.0.
