Memory leaks? Rated 3 out of 5 stars
When I use this extension my CPU eventually soars near 100% and Firefox's memory usage goes well above 1GB. Removing this extension restores Firefox to "normal" CPU & memory stats. I think the developer has done a great job on this extension and like the features very much, but until the memory leaks and CPU usage issues are resolved I can't use it. In the mean time I'm using "Tab Sidebar" to get the vertical tabs UI.This review is for a previous version of the add-on (0.7.2008101801).
