如何添加Firefox书签作为工具栏按钮?
我有一个书签,可用来从网站“使颜色变泽”: javascript:(function(){var%20newSS,%20styles='*%20{%20background:%20white%20!%20important;%20color:%20black%20!important%20}%20:link,%20:link%20*%20{%20color:%20#0000EE%20!important%20}%20:visited,%20:visited%20*%20{%20color:%20#551A8B%20!important%20}';%20if(document.createStyleSheet)%20{%20document.createStyleSheet("javascript:'"+styles+"'");%20}%20else%20{%20newSS=document.createElement('link');%20newSS.rel='stylesheet';%20newSS.href='data:text/css,'+escape(styles);%20document.getElementsByTagName("head")[0].appendChild(newSS);%20}%20})(); 我真的想使其成为Firefox中工具栏上的实际按钮(例如,在“帮助”按钮的右侧)。我知道将其移动到书签工具栏上很容易,但是我希望隐藏书签工具栏,因此宁愿在Firefox中为此设置一个实际按钮,如果方便的话,可能还需要其他一些书签! 如何添加Firefox书签作为工具栏按钮?
