Do you have the @namespace line at the beginning of the css file?

Instead of userChrome, you can hide the Menu Bar:

(although Tools and Help are still on the AppMenu icon, which can be moved off the toolbar)

In TB 68, you may need to switch toolkit.legacyUserProfileCustomizations.stylesheets to true in Config. editor.

First thank you for your response. I have poured over 3 pages deep of google trying to figure this out so I have tried pretty much everything, including everything you have suggested.

The @namespace line is there.

I do not wish to hide the menu bar as that is too easy to get around and we do want them to be able to get to some options. They just do not want them to have access to the tools and help menu.

In TB 68 the toolkit.legacyUserProfileCustomizations.stylesheets is already set to true. It doesn't look like that was actually disabled until 69.

Thanks again,

I tested this css code in TB 68.1:

http://www.linnhe2.free-online.co.uk/thunderbird/chrome.html#Hide%20specific%20menus

Replace Go with Tools, or any other menu item.

This is exactly what I needed thank you so much for the link and all the help it is greatly appreciated!

After reading over this page I can now also remove specific Menu Items which is even better so I can really clean up the other items they do not need access to. So far everything has worked as expected and I have been able to remove most items, however I cannot seem to remove anything that has ... after it for example trying to remove Customize... from the View - Toolbars menu, or even their own example of Subscribe... see below for provided code;

/* hide some menu items */ menuitem[label="Subscribe..."], menuitem[label="Release Notes"], menuitem[label="Customize..."] {

 display: none !important;

}

Seems I am still missing something when it comes to those Menu Items. Any advice would be a great help to me.

Thanks again for solving my initial issue!

I confirm that the code doesn't hide menu items with ..., even if the periods are removed. Perhaps you can contact the author (link on home page).

I am going to try that, for now I will mark this issue as resolved as you have solved my original questions. Thanks again for all the help!

For anyone trying to accomplish locking down TB using a userChrome.css this was my final code. I hope it helps someone else!
