Firefox is an open source browser that features a standards-compliant HTML display engine, tabbed browsing, popup blocking, extensions, improved security, and more. Firefox is based on the Mozilla codebase.

To install the package of the latest release version of Firefox, type:

# pkg install firefox

To instead install Firefox Extended Support Release (ESR) version, use:

# pkg install firefox-esr

Localized versions are available in www/firefox-i18n and www/firefox-esr-i18n.

The Ports Collection can instead be used to compile the desired version of Firefox from source code. This example builds www/firefox, where firefox can be replaced with the ESR or localized version to install.

# cd /usr/ports/www/firefox
# make install clean

Opera is a full-featured and standards-compliant browser which is still lightweight and fast. It comes with a built-in mail and news reader, an IRC client, an RSS/Atom feeds reader, and more. It is available as a native FreeBSD version and as a version that runs under Linux® emulation.

This command installs the package of the FreeBSD version of Opera. Replace opera with linux-opera to instead install the Linux® version.

# pkg install opera

Alternately, install either version through the Ports Collection. This example compiles the native version:

# cd /usr/ports/www/opera
# make install clean

To install the Linux® version, substitute linux-opera in place of opera.

To install Adobe® Flash® plugin support, first compile the www/linux-flashplayer port. Licensing restrictions prevent making a package available. Then install www/opera-linuxplugins. This example compiles both applications from ports:

# cd /usr/ports/www/linux-flashplayer
# make install clean
# cd /usr/ports/www/opera-linuxplugins
# make install clean

Once installed, check the presence of the plugin by starting the browser, entering opera:plugins in the location bar and pressing Enter. A list should appear with all the currently available plugins.

To add the Java™ plugin, follow install java/icedtea-web.

Konqueror is more than a web browser as it is also a file manager and a multimedia viewer. It is included in the x11/kde4-baseapps package or port.

Konqueror supports WebKit as well as its own KHTML. WebKit is a rendering engine used by many modern browsers including Chromium. To use WebKit with Konqueror on FreeBSD, install the www/kwebkitpart package or port. This example installs the package:

# pkg install kwebkitpart

To install from the Ports Collection:

# cd /usr/ports/www/kwebkitpart
# make install clean

To enable WebKit within Konqueror, click “Settings”, “Configure Konqueror”. In the “General” settings page, click the drop-down menu next to “Default web browser engine” and change “KHTML” to “WebKit”.

Konqueror also supports Flash®. A “How To” guide for getting Flash® support on Konqueror is available at http://freebsd.kde.org/howtos/konqueror-flash.php.

Chromium is an open source browser project that aims to build a safer, faster, and more stable web browsing experience. Chromium features tabbed browsing, popup blocking, extensions, and much more. Chromium is the open source project upon which the Google Chrome web browser is based.

Chromium can be installed as a package by typing:

# pkg install chromium

Alternatively, Chromium can be compiled from source using the Ports Collection:

# cd /usr/ports/www/chromium
# make install clean
