Rated 5 out of 5 stars

可以增加側邊分頁的主題嗎?! 或是CSS EDITOR之類的
還有grouping by domain似乎沒有效

This review is for a previous version of the add-on (0.9.9.2). 

I'm sorry, pop-up support and element hiding helper don't work under Firefox 3.6.*. i highly recommend you upgrade to Firefox 11. Official support for Firefox 3.6 will be dropped in 20 days and obviously i can't support an outdated version of firefox although Firefox 10esr could be an exception.
