When I click "Delete Bookmark, nothing happens-the bookmark is not deleted. What gives? I keep Firefox updated when I'm alerted and I have updated to Windows 11.

Why have YOU removed my Bookmarks Sidebar??? I have collected many bookmarks, but NOW there is NOTHING in the sidebar!! This is a rubbish way to update users - STOP IT!! I want my book marks on MY sidebar ... stop thinking YOU KNOW BETTER!! GIVE ME BACK MY BOOK MARKS! WHERE *I* WANT THEM!!

Seriously this is SO RUBBISH I will dump Firefox ... after MANY MANY YEARS!!

Hello, I noticed google rolled out new icons for its workspace. However I use these workspace apps frequently and leave them on my bookmarks bar. For some reason however the docs, slides, and sheets logos respectively have defaulted their icons back to the original google drive icon. making it impossible to tell which is which from a glance. Sorry to bother y'all!

When I click Bookmarks > Manage Bookmarks I'm taken to Other Bookmarks where I never store anything. I'd delete it if I could but it doesn't appear to be an option, so instead I'd like to taken directly to Bookmarks Menu. I came across this post from just over 4 years ago which sounded like it's exactly what I want, but it doesn't work. Are there any changes anyone can suggest that would allow it to work in 2026?

You can use the autoconfig.cfg file in the Firefox installation folder to initialize (set/lock) preferences and run privileged JavaScript code. In this case code to open the Library with the Bookmarks Menu folder selected. You can modify the showPlaces variable to open any of the four possible root folders (in this case [1]).

To use Autoconfig, place two files into the Firefox installation directory.

   on Windows and Linux, they go into the same directory where Firefox is installed
   on macOS, they go into the Contents/Resources directory of the Firefox.app 

The autoconfig.js file that specifies to use autoconfig.cfg is placed into the "defaults\pref" directory where the channel-prefs.js file is located.

The autoconfig.cfg file is placed at the top level of the Firefox directory.

   autoconfig.cfg and autoconfig.js need to start with a comment line (//)
   autoconfig.js needs to use Unix line endings (LF instead of CR/LF)

Content of autoconfig.js

//
pref("general.config.filename", "autoconfig.cfg");
pref("general.config.obscure_value", 0);
pref("general.config.sandbox_enabled", false); // disable sandbox to allow privileged JavaScript

Content of autoconfig.cfg

// first line in autoconfig.cfg is a comment line try {

let {classes:Cc, interfaces:Ci, manager:Cm, utils:Cu} = Components;

function ConfigJS() { Services.obs.addObserver(this, 'chrome-document-global-created', false); }

  let document = aEvent.originalTarget;
  let window = document.defaultView;
  let location = window.location;
  if (/^(chrome:(?!\/\/(global\/content\/commonDialog|browser\/content\/webext-panels)\.x?html)|about:(?!blank))/i.test(location.href)) {
   if (window._gBrowser) {
     let showPlaces = ["AllBookmarks","BookmarksMenu","BookmarksToolbar","UnfiledBookmarks"][1];
     elm = document.getElementById("Browser:ShowAllBookmarks");

      elm.setAttribute("oncommand", "PlacesCommandHook.showPlacesOrganizer('"+showPlaces+"')");
     }
   }
  }
 }
};
if (!Services.appinfo.inSafeMode) { new ConfigJS(); }

} catch(e) {Cu.reportError(e);}

What happens here is my bookmarks still show on the bar, but they show as grey with no color and the URL is blank. I can restore them using Bookmarks/Manage Bookmarks/Import and Backup/Restore, but this is happening at least once a week on both my and my wifes HP Desktops. I am wondering if it may be related to Iolo System Mechanic, which we both use to keep our computers "clean"?

When I click on the star icon in the address bar the star icon is filled in, and existing bookmarks show with the filled-in star icon. But I no longer get a dropdown where I can edit, tag, or delete an existing bookmark, and URLs I click on don't show up in Recently Bookmarked so they haven't been added.

The places.sqlite file in my profile is not read-only, and I restarted Firefox (stupidly, before I took a screenshot of the pinned shortcuts on my new tabs page) and that made no difference.

Thanks in advance for any help!

why did you destroy the existing bookmark structure and replace it with something that makes no sense. I have no idea from where you obtained the url's for the stuff that's in bookmark's now. I also do not look forward to having to re-create all of the bookmarks I had in place. I won't be doing that on Mozilla! R Crider

Every few days the contents of all of my bookmarks in my Bookmarks Toolbar folder are erased. The bookmarks are all there, but none of the books marks has any contents. Of course, it is easy to reload them by restoring bookmarks, but this should never happen in the first place.

Does anyone know why this is happening, and how to fix it?

I'm running Windows 11 Pro and Firefox 151.0.1 (64 bit)

I used to be able to add another site on the top toolbar to the one I am currently on ---- this was on the toolbar at the top of the page. This ability has disappeared recently.

When I click to save a bookmark, the menu that allows you to select the folder to save it to is no longer being displayed. If I click the save bookmark option again, it gives the option to edit the bookmark like it has always done. The bookmark menu then pops up and shows the bookmark is saved in whatever folder you had saved a bookmark in previously. I am on a desktop using windows 11. This has been happening for the last couple of days. I have shutdown the computer and also tried restarting but am still not able to see the selection box when saving a bookmark. I am also current on firefox updates and windows updates.

I am unable to bookmark anything. Some suggestions are to open a new table then type about: profile and then hit restart. When I do that DuckDuck then searches profile.

Hi,

I searched the web for deleting the item "Weitere Lesezeichen" in the sidebar. I found only solutions for the firefox 85. In Firefox 85 should be a field for hiding this. Although in Firefox 150 it can`t be hided or deleted. I don`t need and I don`t want this "Weitere Lesezeichen". Any solutions?
