These are possible chrome URI that you can use to open the Library or the bookmarks panel:

• chrome://browser/content/places/places.xul
• chrome://browser/content/bookmarks/bookmarksPanel.xul

Use the -chrome command line switch if necessary.

• https://developer.mozilla.org/Command_Line_Options

Note that this command will open the Library with the unsorted folder selected:

• PlacesCommandHook.showPlacesOrganizer('UnfiledBookmarks');

You can use an extension like keyconfig to create a shortcut key with this command.

I made a shortcut with this as the Target, and it doesn't work:

"C:\Program Files\Mozilla Firefox\firefox.exe" PlacesCommandHook.showPlacesOrganizer('UnfiledBookmarks');

Do I use -chome if I want to use switches for Chrome that would work in FF? No idea.

For File Explorer, I think you add . . . /e . . . to the end, and it expands the folders . . . any idea what the target is that I should enter? They don't make it very easy to figure out.

PlacesCommandHook.showPlacesOrganizer('UnfiledBookmarks'); is a command and not a link, so you can't use it that way.

Do not get confused by the chrome URL as they have nothing to do with Google Chrome.

You can open such a chrome:// URL via the location/address bar in a tab to see what the page looks like.

Firefox uses the "chrome://" protocol to access its own internal files and also access files from extensions (no connection with Google Chrome).

keywords: firefox target to open library

I see you previously answered it here, my inspirational friend . . . https://support.mozilla.org/en-US/questions/992268

As a Target - this works "C:\Program Files\Mozilla Firefox\firefox.exe" -chrome chrome://browser/content/places/places.xul

I see that the Shortcut doesn't do anything if I leave off the -chrome command line switch.

As a Target - this opens a tiny window in the top left, and the GUI is not complete - no good "C:\Program Files\Mozilla Firefox\firefox.exe" -chrome chrome://browser/content/bookmarks/bookmarksPanel.xul

. . . You can also set the home (startup) page to one of those chrome URL to open the Bookmarks Manager (Library).

I put this in the address bar, and see it, yes, along with other things I'd see viewing a web page, so the Target way of doing it is better: chrome://browser/content/places/places.xul

With this one, same things as above chrome://browser/content/bookmarks/bookmarksPanel.xul

"Note that this command will open the Library with the unsorted folder selected:"

PlacesCommandHook.showPlacesOrganizer('UnfiledBookmarks');

. . . if it's not the Target in a Shortcut, or go in the Address Bar where it can be made into a Bookmark, how do you use it?
