DragonFly BSD



Firefox Extended Support Release is a specific firefox release for organizations.

As of the writing of this document, Firefox ESR is in dports as www/firefox-esr.

Binary package

As root:

# pkg install firefox-esr

Building from source

A Dports checkout/tarball is needed for this, usually you can get it easily by following the instructions in /usr/Makefile:

# cd /usr
# make help

To install:

# cd /usr/dports/www/firefox-esr
# make BATCH=yes install clean

You can also use synth to install it:

# cd ~
# synth install www/firefox-esr


Always check what the pkg-message of the package says. It will give some recommendations for the setup.

# pkg info -D firefox-esr

For Firefox specifically bear in mind that IPC in FreeBSD works differently as it works in DragonFly BSD.


Besides the usual recommendations for web browsing security, we've created also a way of setting up Chromium to minimize the risks of exposure to certain vulnerabilities (Spectre, Meltdown) among other things. Please see: RunSecureBrowser Similar guidelines could be applied to any other browser although they may not have the same security mechanisms Chromium has.
