See if can update it from Tools --> Add-ons page.

Go to the Extension Makers page and check if there are notes there. Are the developing for Firefox 57 release or stopping.

Search for a " comparable " replacement.

Note : Firefox 56.0.2 is current release https://www.mozilla.org/firefox/all/ Full Version Installer Note : Firefox 57 Quantum release date Nov 14th https://www.mozilla.org/en-US/firefox/quantum/ Note : Legacy Extensions will be disabled and or removed.

Please let us know if this solved your issue or if need further assistance.

The makers page says this will no longer be supported and I have searched for a replacement with no success. I was hoping by posting here I would get recommendations for a replacement.

Don't despair, you can use a custom style rule to let the bookmarks toolbar "wrap" to additional lines. How many lines do you need?

I started from the following rule, and experimented with settings until I found something that seemed reasonable.

https://www.reddit.com/r/firefox/comments/75wya9/multiple_row_bookmark_toolbar_for_firefox_5758/doa006c/

Implementing a custom style rule does involve some poking and prodding, but if you have several minutes, you can do it. I've got the steps for creating a userChrome.css file on Windows in another thread, but I think Finder works a bit differently, so you might need to improvise a bit. cor-el also posted useful information:

https://support.mozilla.org/questions/1180489

And here's the suggested code:

@-moz-document url(chrome://browser/content/browser.xul) {
  /* Multi-Row Bookmarks Toolbar */
  #PersonalToolbar {
    /* Provide room for up to 4 rows at 26px */
    max-height: 104px !important;
  }
  #PlacesToolbarItems > box {
    display: inline-block !important;
  }
  #PersonalToolbar #PlacesToolbarItems {
    /* Override hiding */
    overflow-x: visible !important;
    overflow-y: visible !important;
    /* Add a little cushion */
    padding-bottom: 1px;
  }
  #PersonalToolbar #PlacesToolbarItems .bookmark-item {
    /* Reduce padding on individual bookmarks to fit rows closer together */
    padding-top: 1px !important;
    padding-bottom: 1px !important;
  }
}
 

I don't know what other features of the extension you were using, but some of those might also be possible.

While I may try this as I used to be a programmer I would rather install an app of some sort to do this for me. Does anyone out there know how firefox is going to support multi row bookmarks after version 57?

Check this out.

cant find userChrome.css in mac OS

Hi ahmedharris

The chrome folder and the userChrome.css (user interface) and userContent.css (web content) files do not exist by default.

You need to create the chrome folder (lowercase) in the <xxxxxxxx>.default profile folder if this folder doesn't exist

• use a plain text editor (Windows: Notepad; Mac: Textedit) 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 the userChrome.css file starts with the default @namespace line

If you are on Windows:

• make sure you select "All files" and not "Text files" when you save the file via "Save file as" in the text editor as userChrome.css.

Otherwise Windows may add a hidden .txt file extension and you end up with a not working userChrome.css.txt file.

• make sure you do not have a double .css.css file extension (userChrome.css.css) if it is still not working

@ahmedharris

Help -> Troubleshooting information > Profile Directory -> Open Directory

After that, directory should be opened. Try to locate "chrome" directory there. If it is not present, create it and enter it. That is the place where you should put your userChrome.css (chrome/userChrome.css). So if it is there, just edit it. If it isn't, create it and put the content you want.

copied the text and saved in the folder but still not getting multiple row.

got it its working..
