Not effective.

Stack function sometimes just stick to the right side as a line.

Sometimes doesn't work properly in google image.

In loading some of the web pages, it is even slower than directly opening in a new tab.

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

Version 2.7 coming soon!

Version 2.6.4 does not have a stack function. We had to take it out when we moved to FF3. The good news is that we have a new version 2.7 that will be posted here very shortly, that not only has the stack function but also has a number of performance enhancements. :) If you can't wait, please visit coolpreviews.com. Thanks for posting. We appreciate your feedback.
