Removal of New "List All Tabs" Button.
A new version of the "List All Tabs" appeared on my toolbar today, shown on the left and hovered over in the attached screenshot (ignore the Malwarebytes extension icon). The old icon for this button was a chevron with approximately the same functionality. I was able to remove the old icon, but I'm unable to find a way to remove this one. Here is what I've tried so far:
- Like the old one, the Customize Toolbar feature is unable to remove it since it is grayed out.
- For a while, I was able to remove the old icon by going to about:config and setting browser.tabs.tabmanager.enabled to false. This solution does not work for the current and some recent versions of the button.
- I attempted to create a userChrome.css file (following all the steps according to this this website) and added the following string: #alltabs-button { display: none !important; }
None of these attempted fixes have removed the button following a browser restart. Is there a way to remove it? I have no need of a button that shows me what tabs I have open when I can simply look at my toolbar.

Setting browser.tabs.tabmanager.enabled to false still works in the old way, meaning that the button is hidden by default and is shown if the number of open tabs exceeds a limit.
Using #alltabs-button { display: none !important; } in userChrome.css also should still work.
It is not that difficult to create userChrome.css if you have never used it, so you can check that you created userChrome.css properly.
The first step is to open the "Help -> Troubleshooting Information" page and find the button to access the profile folder with the random name (xxxxxxxx.default-release).
You can find the button to go to the profile folder 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 the profile folder with the random name (name is all lowercase). In the chrome folder you need to create a plain text file with the name userChrome.css (name is case sensitive). In this userChrome.css text file you paste the text posted. On Mac you can use the TextEdit utility to create the userChrome.css file as a plain text file.
In Windows saving the file is usually the only time things get more complicated because Windows can silently add a .txt or .css file extension and you end up with a file like userChrome.css.txt or userChrome.css.css. To avoid this, you need to make sure to select "All files" in the "Save File" dialog in the text editor.
You need to close (Quit/Exit) and restart Firefox when you create or modify the userChrome.css file.

You need to set this pref to true in about:config to enable userChrome.css and userContent.css in Firefox 69+.

Although setting browser.tabs.tabmanager.enabled to false in about:config still does not work (tested multiple times between browser and system restarts), repeating cor-el's steps to access my profile folder uncovered my mistake. I originally went to about:profiles and opened the Local path of my profile folder instead of the Roaming path, and created the userChrome.css file there.
After moving the chrome folder I created from Local to Roaming, the .css file began working.
