Install Firefox 135 on Linux system

Many Linux distributions have Firefox installed by default. If you need to install it using other methods, this guide will show you several alternative ways to download and install Firefox on Linux.

Install Firefox using your package manager (recommended)

This method is recommended because it ensures that Firefox and all necessary libraries are correctly installed and configured to your system.

However, there may be a slight delay between the release of the new Firefox and the update of its packages by your distribution.

Additionally, your distribution may be available without the Firefox brand identity, or only ESR (extended support version).

 <code>sudo apt install firefox [在**Debian、Ubuntu和Mint** 上] sudo yum install firefox [在**RHEL/CentOS/Fedora** 和**Rocky/AlmaLinux** 上] sudo emerge -a sys-apps/firefox [在**Gentoo Linux** 上] sudo apk add firefox [在**Alpine Linux** 上] sudo pacman -S firefox [在**Arch Linux** 上] sudo zypper install firefox [在**OpenSUSE** 上] sudo pkg install firefox [在FreeBSD上]</code>

Ubuntu users can always get the latest version of Firefox through the default Ubuntu update channel. But the upgrade is not available yet, if you want to give it a try, there is an official Mozilla PPA for testing new versions of Firefox on Ubuntu and its derivatives.

 <code>sudo add-apt-repository ppa:mozillateam/ppa sudo apt update sudo apt install firefox</code>

Install Firefox using Flatpak

To install Firefox from Flatpak, you need to install and configure Flatpak on your Linux system. After installing Flatpak, go to the Firefox Flathub page and click the "Install" button.

Alternatively, you can type the following command in the terminal:

 <code>flatpak install flathub org.mozilla.firefox</code>

Install Firefox using Snap

To install Firefox from Snap, you need to install Snap on your Linux system. After installing Snap, go to the Firefox Snapcraft store page, click the "Install" button and follow the instructions.

Alternatively, you can type the following command in the terminal:

 <code>sudo snap install firefox</code>

Manually install Firefox using binary package

To install the latest version of Firefox, visit the official Mozilla Firefox download page and click the button to download the latest version suitable for your system architecture.

Next, navigate to the directory where you saved the downloaded file, unzip the archived contents, and move the unzipped firefox directory to the /opt directory as shown below.

 <code>tar xjf firefox-*.tar.bz2 sudo mv firefox /opt</code>

Now, use the following command to create a symbolic link to the Firefox executable in /usr/local/bin .

 <code>sudo ln -s /opt/firefox/firefox /usr/local/bin/firefox</code>

To make Firefox appear in your application menu, create a desktop entry.

 <code>sudo nano /usr/share/applications/firefox.desktop</code>

Add the following to the file.

 <code>[Desktop Entry] Name=Firefox Comment=Web Browser GenericName=Web Browser Exec=/opt/firefox/firefox %u Icon=/opt/firefox/browser/chrome/icons/default/default128.png Terminal=false Type=Application Categories=Network;WebBrowser; MimeType=text/html;text/xml;application/xhtml xml;application/xml;application/vnd.mozilla.xul xml;application/rss xml;application/rdf xml;</code>

Save and close the file (using Ctrl O , Enter, Ctrl X in nano).

Finally, you can now start Firefox with the following command.

 <code>firefox</code>
