Rated 4 out of 5 stars

You MUST develop an upgrade for quantum, another guy "inspired" by your work tried to do the same, but this add-on it's just unique and i have been enjoying it for a long time, as I tended to close firefox, but many times I lost my info before I intall this one,

This review is for a previous version of the add-on (0.8.1.13).
