Ever noticed that small button in Firefox showing all your open tabs? “List All Tabs” button does one thing—lists every tab you’ve opened. Sounds harmless, but it can clutter the tab bar and cramp your browsing space. The worst part? You can’t simply remove it, at least not with a basic Firefox setting. The people at Mozilla thought we needed it, whether we like it or not.
A Firefox developer once explained it like this: the button keeps a hidden tabs menu. It’s a safety net to catch any sneaky add-ons that could hide tabs from you. Mozilla thinks it’s safer to leave the button there, even if most of us won’t need it.
So, Firefox won’t let you remove it directly. But there are two tricks that still work to remove the “List All Tabs” button.
Method 1: Use about
Sadly, this method only worked until version 108. But if you’re on an older version, here’s what you’d do:
- Open Firefox and type about:config in the URL bar.
- Hit “Accept the Risk and Continue.”
- Use Ctrl + F and search for this flag: browser.tabs.tabmanager.enabled.
- Change the value from “True” to “False.”
- Restart Firefox, and the button should disappear.
Method 2: Use Custom CSS
This one still works:
- Click the hamburger menu (the three horizontal lines).
- Select “Help,” then “More troubleshooting information.”
- Go to the Profile Folder, then hit “Open Folder.”
- Create a new folder called “chrome.”
- Inside that, create a file called userChrome.css. (Make sure it’s saved as a CSS file, not TXT.)
- Open this file in Notepad and type:
#alltabs-button { display: none !important; }
- Save the file and close Notepad.
- Go back to Firefox and type about:config in the URL bar.
- Search for toolkit.legacyUserProfileCustomizations.stylesheets.
- Change the value to “True” and restart Firefox.
And there you go! That little button should be gone for good.
Dealing with things like this in Firefox can be frustrating. But a little tweak here and there can make your browser feel like yours again.
