Rated 5 out of 5 stars

I update firefox to version 29, when I use the addon "classic theme restorer" to move the star button to urlbar, "stay-open menu" become disabled.

I also use Classic Theme Restorer to move the star to the location bar. This changes the 'bookmarks button' to CTR's version which has a different id. Version 3.0 (currently on the development channel) is already compatible with this; versions prior to 2.3 are not. Version 2.3 can be made compatible by editing the about:config pref as described at
