I want the bookmark toolbar appears when I move my cursor to the top of screen, when I in fullscreen mode.

The bookmarks in the bookmark toolbar is the most frequently used bookmarks, so I need to visit them frequently.

I'm also using Vimperator, is there a command that only list out the bookmarks in bookmark toolbar?


I haven't tried it myself but here is a link that says you need a firefox addon. https://support.mozilla.org/en-US/questions/1039009

  • The link you provided is very useful, I've solved this problem using the code they provided, not an extension – an offer can't refuse Jun 21 '15 at 15:45
  • Could you please edit in the useful code/extension links? The link to the forum could change, or otherwise go dead, meaning this answer wouldn't be useful then. – Wilf Jun 21 '15 at 15:46
  • @Wilf I've add the method, you can try it. – an offer can't refuse Jun 21 '15 at 15:58

The code is below, it is from mozilla support forum:

@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); /* only needed once */

/* full screen toolbars */
#navigator-toolbox toolbar[moz-collapsed="true"]:not([collapsed="true"]) {


  • Create the chrome folder (lowercase) in the .default profile folder if this folder doesn't exist. The <xxxxx>.default folder is under ~/.molliza/ folder, i.e. where firefox stores its profiles. <xxxxxx> is some weried strings different for each computer.

  • Use a plain text editor like vim to create a (new) userChrome.css file in the chrome folder (file name is case sensitive)

  • Paste the code in the userChrome.css file in the editor window Make sure that the userChrome.css file starts with the default @namespace line

The problem is solved.


As of Firefox 68, Firefox does not (by default) check for a custom userChrome.css file. Thus, the was I solved this problem on my computer was in two steps.

1. Create userChrome.css

In ~/.mozilla/<profile code>.<profile name>/ create a directory named chrome. In the chrome directory, create a file named userChrome.css with the following contents:

   Override hiding of Bookmarks Toolbar in F11 full screen
   when you roll down the tabs/main toolbar 
    src: https://support.mozilla.org/en-US/questions/1212156?fpa=1
    and https://www.userchrome.org/how-create-userchrome-css.html
#navigator-toolbox[inFullscreen="true"] #PersonalToolbar {
  visibility: unset !important;

2. Configure Firefox to look for userChrome.css at startup.

Copied from userchrome.org.

To make startup faster for most users, Firefox 69 will no longer look for this file automatically. You need to tell it to look. Here's how:

  1. In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button accepting the risk.
  2. In the search box above the list, type or paste userprof and pause while the list is filtered. If you do not see anything on the list, please ignore the rest of these instructions. You can close this tab now.
  3. If the toolkit.legacyUserProfileCustomizations.stylesheets preference is not already set to true, double-click it to switch the value from false to true.

That change should take effect on your next startup.
