Still Bug in 1.5.6 Rated 5 out of 5 stars

Hi, this is a great Addon, but i have still two bugs:
- Pixel Perfect Tab just opens on webpages, where i had already added a layer.
- Deleting layers doesnt work properly. After restart of firefox, the deleted layers appears again.
Tested on Firefox 3.5.8, Firebug 1.5.3, Pixel Perfect 1.5.6

This review is for a previous version of the add-on (1.5.6).
