Make it possible to roll back, because the latest version is a mess.

Visually I don't find the new version appealing, since it's made my thumbnails harder to identify by zooming them in too far and blurring them.  Also, this version introduced a delay before loading when I'd open my web browser and it wouldn't appear at all in new tabs, but once I set it up to open in new tabs it would no longer open when I first loaded up my web browser even though it's set as my homepage.  This add-on was working fine until the latest update and I'd just like to roll back until it's fixed.  Or forever.
