Hi, since Firefox 57 Quantum, you may have to enable the bookmarks button: Open the 3-bar menu > Library > Bookmarks > Bookmarking tools, and click Add Bookmarks Menu to Toolbar - see Bookmarks in Firefox. If you don't see it on the toolbar, go to the 3-bar menu > Customize, and look for it in the palette, from where you can drag it to a toolbar. If the button is still missing, try clicking on Restore Defaults. More Customize Firefox controls, buttons and toolbars.

The bookmarks sidebar can be dragged to resize (Ctrl+B); as can the Bookmarks Library (Ctrl+Shift+B).

If you mean the bookmarking dropdown from the star, it might be possible to do that with userChrome.css. Here's somewhere to look/ask:

Hi, thanks for reply much appreciated, however it is related to being able to drag the window size (something a now defunct extension allowed you to do) in the bookmarking dropdown from the star.

Currently you have to scroll down the side everytime you want to find a different folder as you cant extend the window size down. To have to change the userChrome.css is not a solution. When would you encounter a window that you cant scale, what reasoning would there be for not having it.....its basic functionality thats missing.

I have to add as well that more and more these days software is written half finished with a kind of expectation that everyone wants to write code, I dont, I want to simply scale the window like every other window ..since the beginning of time, we all know this  ;)

Hi, can you please take a screen shot https://support.mozilla.org/en-US/kb/firefox-screenshots of this as I do not visualize what you are getting at, as I use the star from the taskbar and also have the old Menu Bar open at the top of the browser. I tend to use that more, plus quicker to get to a full page Show Bookmarks. Thanks.

The 'window' that opens if you click the star on the location/address bar is a doorhanger and not a real window. Your only option to adjust the dimensions of a doorhanger is to use code in userChrome.css.

What is against using this file to modify the appearance of elements in the user interface?

It is not that difficult to create userChrome.css if you have never used it.

The first step is to open the "Help -> Troubleshooting Information" page and find the button to access the profile folder.

You can find this button under the "Application Basics" section as "Profile Folder -> Open Folder". If you click this button then you open the profile folder in the Windows File Explorer. You need to create a folder with the name chrome in this folder (name is all lowercase). In the chrome folder you need to create a text file with the name userChrome.css (name is case sensitive). In this userChrome.css text file you paste the text posted.

In Windows saving the file is usually the only time things get more complicated because Windows can silently add a .txt file extension and you end up with a file named userChrome.css.txt. To avoid this you need to make sure to select "All files" in the dialog to save the file in the text editor using "Save File as".

You need to close and restart Firefox when you create or modify the userChrome.css file.

Add code to the userChrome.css file below the default @namespace line.
