How Do I Uninstall Firefox From Ubuntu?

If you’re an Ubuntu user looking to streamline your system or switch to a different web browser, knowing how to uninstall Firefox can be a handy skill. Firefox, being one of the most popular browsers pre-installed on many Linux distributions, including Ubuntu, sometimes needs to be removed for various reasons—whether it’s to free up space, resolve conflicts, or simply try out alternatives. Understanding the proper way to uninstall Firefox ensures your system remains clean and functional without leftover files or dependencies.

Uninstalling software on Ubuntu isn’t always as straightforward as it might seem, especially when dealing with default applications like Firefox. The process involves using command-line tools or graphical package managers, each with its own nuances. Additionally, depending on how Firefox was installed—whether through Ubuntu’s standard repositories, a snap package, or other means—the removal steps can vary. This overview will help you navigate these differences and prepare you for a smooth uninstallation experience.

In the following sections, you’ll find clear, step-by-step guidance tailored to different installation methods, along with tips to verify the removal and manage any residual files. Whether you’re a Linux beginner or a seasoned user, this article will equip you with the knowledge to confidently uninstall Firefox from your Ubuntu system.

Removing Firefox Using the Terminal

Uninstalling Firefox through the terminal is a straightforward process that leverages Ubuntu’s package management system. This method provides precise control over the removal process and is often preferred by users who want to ensure all associated files are cleanly removed.

To begin, open your terminal by pressing `Ctrl + Alt + T` or searching for “Terminal” in the application menu. The primary command used to uninstall Firefox is `apt-get remove` or `apt remove`. However, to remove Firefox along with its configuration files, the `purge` option is recommended.

Execute the following command to uninstall Firefox while purging configuration files:

“`bash
sudo apt-get purge firefox
“`

This command will prompt for your administrator password and proceed to remove Firefox and its related system configuration files. To confirm the removal, you may be asked to approve the operation by typing `Y` and pressing Enter.

After purging Firefox, it is prudent to remove any unused dependencies that were installed alongside it but are no longer necessary. This can be done with:

“`bash
sudo apt-get autoremove
“`

This cleans up any orphaned packages, freeing up disk space and maintaining system hygiene.

Uninstalling Firefox Installed via Snap

Ubuntu often installs Firefox as a Snap package by default, especially in newer releases. The Snap system isolates applications for security and ease of updates, but it requires a different approach for uninstallation.

To check if Firefox is installed as a Snap package, run:

“`bash
snap list | grep firefox
“`

If Firefox appears in the list, you can remove it using the Snap command:

“`bash
sudo snap remove firefox
“`

This command removes the Firefox Snap package entirely. Unlike `apt` packages, Snap packages do not require an autoremove step since Snap handles dependencies internally.

Manual Removal of Firefox Configuration and Cache Files

Even after uninstalling Firefox using either `apt` or Snap, some residual files related to user profiles, caches, and settings remain in your home directory. These files do not affect system stability but can consume disk space.

To remove these manually, navigate to your home directory and delete the following folders:

`.mozilla/firefox/` – Contains user profiles and preferences.
`.cache/mozilla/firefox/` – Stores cached data for faster browsing.

Use the following commands to remove these directories:

“`bash
rm -rf ~/.mozilla/firefox/
rm -rf ~/.cache/mozilla/firefox/
“`

Be cautious when using `rm -rf` as it permanently deletes files. Make sure you have backed up any important bookmarks or settings before proceeding.

Comparison of Removal Methods

The table below summarizes the key differences between uninstalling Firefox using `apt` and Snap, including manual cleanup considerations:

Method	Command	Removes Configuration Files	Requires Manual Cleanup	Dependency Handling
APT (Advanced Package Tool)	`sudo apt-get purge firefox`	Yes, with purge option	Yes, user profile and cache remain	Yes, using `autoremove`
Snap	`sudo snap remove firefox`	No, Snap does not purge configs	Yes, user profile and cache remain	Handled automatically by Snap

Additional Tips for Firefox Removal

Backup Important Data: Before uninstalling, export your bookmarks and save any essential data from Firefox profiles.
Check for Multiple Versions: If you have both Snap and APT versions installed, ensure removal commands are executed for both to avoid conflicts.
Alternative Browsers: Consider installing other browsers like Chromium or Brave if you plan to replace Firefox.
System Updates: After uninstallation, running a system update can help synchronize package information:

“`bash
sudo apt-get update && sudo apt-get upgrade
“`

This practice ensures your system remains secure and up to date following software changes.

Uninstalling Firefox Using the Terminal

Removing Firefox from an Ubuntu system can be efficiently accomplished through the command line. This approach provides granular control and immediate feedback on the uninstallation process.

To uninstall Firefox, follow these steps:

Open the Terminal by pressing Ctrl + Alt + T or searching for “Terminal” in the applications menu.
Ensure your package list is up to date with the command:

sudo apt update

Next, to remove Firefox, execute the following command:

sudo apt remove firefox

This command removes the Firefox package but preserves user data and configuration files. To remove Firefox completely, including configuration files, use:

sudo apt purge firefox

After removal, it is advisable to clean up any unused dependencies that were installed alongside Firefox:

sudo apt autoremove

Command	Description
`sudo apt update`	Refreshes package lists to ensure current versions are known.
`sudo apt remove firefox`	Uninstalls Firefox but keeps user settings and data.
`sudo apt purge firefox`	Uninstalls Firefox and removes related configuration files.
`sudo apt autoremove`	Removes dependencies no longer required by any installed package.

If Firefox was installed via Snap (common in recent Ubuntu releases), the removal process differs slightly. Verify Firefox installation method with:

snap list | grep firefox

If Firefox appears in the Snap list, remove it using:

sudo snap remove firefox

This command uninstalls the Snap package of Firefox and its associated data.

Removing Residual Firefox Configuration and Cache Files

Uninstalling the Firefox package or Snap does not automatically delete user profiles, cache, or configuration files. To fully remove Firefox-related data, manual deletion of these files is necessary.

Common locations for Firefox data include:

~/.mozilla/firefox/ – Contains user profiles and settings.
~/.cache/mozilla/firefox/ – Stores cached web content.
~/.config/firefox/ – May contain additional configuration files, depending on setup.

To delete these directories, use the following commands in Terminal:

rm -rf ~/.mozilla/firefox  
rm -rf ~/.cache/mozilla/firefox  
rm -rf ~/.config/firefox

Caution: This action is irreversible and will permanently erase all Firefox user data, including bookmarks, saved passwords, and extensions.

Verifying Firefox Removal

After completing uninstallation and cleanup, confirm that Firefox is no longer present on the system.

Verification Method	Command	Expected Result
Check installed packages	`dpkg -l \| grep firefox`	No output indicating Firefox is installed.
Check Snap packages	`snap list \| grep firefox`	No output indicating Firefox Snap is present.
Attempt to launch Firefox	`firefox`	Command not found or similar error message.

If any of these commands return information indicating Firefox is still installed, repeat the removal steps accordingly.
