Rated 4 out of 5 stars
Almost perfect. But, with one bug.
1) In disablemenu setted "autohide" and "show on mouseover" to "0".
2) In firefox "bookmarks toolbar" is on.
3) Using RSS feeds as bookmarks.
When I try to read a RSS and get with my mouse over top of the window enables menu.
For more details just write me a mail.
