Rated 5 out of 5 stars

Thank you for a dedicated Linux version!

Glitches:

1. Menu shadow looks ugly - when a menu is selected its color changes to white, and shadow is gray - that looks terrible.

2. User Agent Switcher icon appears twice.

3. Help -> About, Close button has a chain line frame inside a button.

This review is for a previous version of the add-on (0.5.6).
