Rated 5 out of 5 stars
There is a new Beta Application that I found called Tab Cloud that appears to work in a similar fashion as Cluster Tabs. I have downloaded, installed and tried Tab Cloud and am fairly satisfied with the end results. I am, however, very sad that I can't gain access to all my clusters that I created over the past year.
Good luck. Please post if you find any other apps that appear to perform the same as Cluster Tabs.
THANK YOU Cluster Tab developers! What a great product. I hope you do consider re-vamping Cluster Tabs to work with FF4. It is an exceptional concept and you were the forefront in creative design. You are sorely missed...
