All bookmarks have grey folders-update 56

more options

I am currently on version 55.0.3 and have had the offer of an update to 56. I accepted the update, installed and restarted FF only to find that all the bookmark foders are grey [not yellow] and a piece of 'unwanted' software [something to do with screenshots] had an icon in the top right-hand corner. I note that doing a search for this problem on this forum, that in a post by WorriedFred on 9.28.17 @ 7.20pm, a post has been marked 'chosen solution'??? There is no solution - if there is where is it??? OR perhaps this is a new default colour style Mozilla have decided to use with this update - how inconsiderate not to mention this if it is so. And to add on a bit of software without permission is a disgrace.

If there has been an official response/explanation for this problem/bug could somebody please point me to it - I have run out of perming 56-bookmarks-grey-all-update in the search Mozilla bar. For the moment I have done a system restore back to 55 - nice yellow forders.

Chosen solution

I’ve been fiddling a bit with some CSS code (also to be found on the net somewhere else) and the following appears to be rather satisfactory so far. The code simply fills and modifies colors for the changed and mainly affected Bookmarks related folder icons in the Firefox 56 Sidebar and Library, as well as the Bookmarks Toolbar items in upcoming 57.

  1. Click the menu button New Fx Menu, click help Help-29 (or press Alt, choose Help in the menu bar) and select Troubleshooting Information. You will be taken to a page with the address about:support (you could enter that in the address bar instead.)
  2. Next to Profile Folder, click Open Folder or Show in Finder or Open Directory (for Win/Mac/Linux). This is the Profile folder.
    On Mac, a folder will open that contains your profile folder. Open the selected profile folder (it will be named something like xxxxxxxx.default for a default profile).
  3. If it isn’t there yet, create a subfolder called chrome.
  4. Go into that folder and create a new text file called userChrome.css if it isn’t there yet.
  5. Copy and paste the following code into the userChrome.css file (or add it if already present, except for the first line), save the file and restart Firefox.

@namespace url(;

.bookmark-item[container], treechildren::-moz-tree-image(container) {

 fill: gold !important;

treechildren::-moz-tree-image(container, OrganizerQuery_BookmarksToolbar) {

 fill: black !important;

treechildren::-moz-tree-image(container, OrganizerQuery_BookmarksMenu) {

 fill: black !important;

treechildren::-moz-tree-image(container, OrganizerQuery_UnfiledBookmarks) {

 fill: black !important;

treechildren::-moz-tree-image(container, livemark) {

 fill: orange !important;

treechildren::-moz-tree-image(container, query) {

 fill: dimgray !important;


(Note that when pasting, some empty lines one may see (1, 6, 8, 11, ...) can be omitted - some breaks were added just for formatting/readability in this forum.)

Although the colors will not be 100% similar to what is used up to 55, they are easy to customize (see here for allowed colors), which may be needed for black/gray items when changing to a dark theme (more relevant to 57.) It actually works quite well for me in both 56 and 57 and offers more customization for the affected items than possible by default in pre 56 versions, since some items can have their own color specified.

The code may not be perfect and/or could be improved - there will probably be various ways to set this up - and of course I could edit the post if there is something really bad in there. It should however be a nice and easy start for those who want it so badly, and can be set up within a minute. Use at your own risk, though nothing should be able to break Firefox.

Hope this helps.

I do not use Chrome. I think I will just go back to the previous version of Firefox unless someone has a fix that will work for me.

Classic Theme Restorer Add-on developer, Aris has released userChrome.css files that modify Firefox 57’s Photon UI. I highly recommend that you give it a try. It's a work in progress with minor tweaks added almost every day but I'm happy with it just the way it is now. It's easy to install. Just download the zip file, extract and put the files into the FF profile chrome folder.

Hi quatrain1, what's Chrome got to do with it?

Please don't confuse the word chrome -- which Mozilla has used for over 15 years to refer to the user interface parts of its browsers -- with the products of a company that liked it so much they named a bunch of products after it.

(1) Create a chrome folder in your Firefox settings. It's Steps #1-3 in this page:

(2) Choose a style recipe:

(A) For coloring the new icons:

Use the download link to save the

file to your system, and move it into your new chrome folder.

You can right-click > rename the file and shorten its name to userChrome.css

(B) For using the old icons:

Use the download link to save the

file to your system, and move it into your new chrome folder.

Extract the files to that folder using your archiving program (e.g., WinZip, WinRar, 7-zip).

Right-click > rename to shorten the file name of userChrome-STARTER.css to userChrome.css

(3) Exit/Quit Firefox and start it up again to see the results.

thank you for your reply's regarding the grey icons. I think I would rather go back to version 56 as I don't like anything at all on 57.

from what I read I would completely delete firefox through the control panel and then download version 56. will I loose my bookmarks? TY

Hi quatrain1, there are no guarantees. Make a backup: Back up and restore information in Firefox profiles.

There is another method described in this article: Uninstall Firefox from your computer

If that doesn't work, Firefox usually installs into one of these two folders (varies based on 32-bit/64-bit). You can check both locations and remove the whole Mozilla Firefox folder(s).

  • C:\Program Files\Mozilla Firefox
  • C:\Program Files (x86)\Mozilla Firefox

OMG it just reverted back to version 57!! What can I do

Did you change your automatic update settings?

  • Windows: "3-bar" menu button (or Tools menu) > Options
  • Mac: "3-bar" menu button (or Firefox menu) > Preferences
  • Linux: "3-bar" menu button (or Edit menu) > Preferences
  • Any system: type or paste about:preferences into the address bar and press Enter/Return to load it

Scroll down on this panel to the updates section. I use "Check for updates but let you choose to install them." Then I get something like the attached when an update is available.
