Rated 4 out of 5 stars

While the latest update solved the problem of not being able to rearrange tabs, in seems to have some new bugs and disimprovements:

1. One must now click on the little X in the upper right corner of the slider to close it. Before, clicking anywhere on the slider would close it.

2. Why the delay and slow fade-out after clicking the X for the slider to disappear? This is annoying if the slider is obscuring something on the page that one is looking at.

This review is for a previous version of the add-on (2.1.5.5).
