about:config search bar missing

citycreek 已回复

I have Firefox 15.3.0.1 on two computers. One one, when I go to about:config, there is a search bar with an option to "Show only modified preferences." On the other computer this search bar is missing. How can I make it display on the second computer?

选择的解决方案

I found the answer to my own question. I had customized the user.css file (in the Chrome folder) in my profile to add this line:

  #toolbar { display:none !important; }


What I should have done is specify a URL so it was not applied to all pages, e.g.

  @-moz-document domain(www.gutenberg.org) {

      #toolbar { display:none !important; }
  }
