# How to remove the x from Firefox tabs

Have you ever accidentally closed a very important tab in Firefox? Lost tons of work and time?

Well, so have I. And I HATE it.

A while back I tried using [Vivaldi](https://vivaldi.com/), a chromium-based browser that boasts "unrivaled customization options" simply because it would allow me to remove the annoying, easily clicked X-to-close button.

However, as with all chromium-based browsers, I inevitably got sick of the instability and gluttonous resource usage, and so I reverted to Firefox, AGAIN.

With this came back the same issue, the damn X-to-close button that I accidentally hit 10 times a day.

BUT, after some digging, I found that removing the X-to-close button in Firefox is entirely possible, and not too hard either!

So, here I am, sharing the love and showing you how to do that. Let's get started:

1\. Type `about:support` into your address bar and press `Enter`

2\. Locate the `Profile Folder` option and click `Open Folder`

3\. Create a new folder called `chrome` (this is case-sensitive)

4\. Now, go to [userChrome.org](https://www.userchrome.org/download-userchrome-css.html) and click `Generate CSS file`

5\. After downloading the file, open it in a text editor and remove everything

6\. Now, paste the following into the file and save it as `userChrome.css`

```css
/*** Hide Tab Close buttons ***/ 
.tabbrowser-tab .tab-close-button {
 visibility: hidden !important; 
}
```

7\. Copy the `userChrome.css` file into the `chrome` directory you created in step 3

8\. Restart Firefox and voila, no more X-to-close button
