Frequently Asked Questions



Profiles, plugins, extensions...




The -private flag does not work in Pale Moon.

The -private flag is designed in this way so as not to tell the user that Pale Moon is in private browsing mode. Try the -private-window flag instead.

HTML5 videos do not work!

Pale Moon requires FFmpeg (specifically the libavcodec component) to play HD H.264 videos. If you're having trouble getting HD HTML5 videos to play, please ensure that you have the libavcodec package installed on your system. Note that on some distros, you will need to install libavcodec from a "non-free" repo.


Pale Moon does not work on my computer!

Please run it from the terminal and see what error message you get.
If you get:

  • palemoon: No such file or directory Make sure you downloaded the correct architecture for your OS. To determine the OS architecture, type uname -m in the terminal.
  • (other errors) - Check whether you meet the system requirements.

Can I install Pale Moon for myself only?

Yes, it is possible to do so. Follow the manual installation method in the installation instructions, and extract the archive to somewhere in your home directory (instead of /opt), and make the menu entry in ~/.local/share/applications. Adjust the additional locations mentioned in the instructions accordingly.

Profiles, plugins, extensions...

Where is the profile of Pale Moon located?

It is located in ~/.moonchild productions/pale moon (note the spaces).

Pale Moon cannot access my profile.

Failure to read the profile can happen due to two reasons:

  • A corrupted profile

In the case of a corrupted profile, check your profile folder for correct paths in the profile.ini file.

  • No read/write permissions

Run the following in the terminal:

    sudo chown -hR $USER: ~/.moonchild productions
    chmod -R +rw ~/.moonchild productions

My plugins do not show up in Pale Moon.

Pale Moon checks for plugins in /usr/lib/mozilla/plugins. Some distros place the plugins in /usr/lib/nsbrowser/plugins. If this is the case and Pale Moon is unable to find your plugins, you can do the following to symlink to the actual plugin directory:

cd /usr/lib
mkdir mozilla
cd mozilla
ln -s ../nsbrowser/plugins plugins

If instead you need to put your plugins in a custom location, you can export MOZ_PLUGIN_PATH=:...

You can also put these export statements in /etc/profile, should you need them to work for all users.

Installing Flash

It is preferable to install Flash from your distros official repositories if possible. Sometimes a "non-free" branch must be enabled in the package management tool to get closed source software through the repositories.


Pale Moon reads the standard Firefox directories for global extensions, thus extensions may be globally installed. Extensions may be extracted into /usr/share/mozilla/extensions/ or, for a specific user, in ~/.mozilla/extensions

It should be noted that Pale Moon is equivalent to Firefox 24 ESR from an extension compatibility point-of-view, although due to the unique GUID of the browser, some extensions may not work. More details can be found here.


Pale Moon's menu entry does not show up or work properly.

  • If the icon does not appear, update the icon cache by running the following:
    sudo gtk-update-icon-cache -f /usr/share/icons/hicolor
  • With some window managers you will have to run a command to update the menu entry. Please refer to the help pages and manuals for your window manager.
  • If the menu entry tries to open "www.%u.com", then your window manager/desktop environment is not compliant with the freedesktop.org standards. A workaround would be to use Exec=palemoon instead of Exec=palemoon %u in the menu entry file.
  • If the menu entry appears across multiple categories, then your window manager does not see the multiple categories as a priority preference. A workaround would be to use Categories= instead of Categories=,... in the menu entry.

Pale Moon crashes if I try to click on any of the menus (File, Edit...)

This is not a Pale Moon problem, but rather a known bug with some versions of the "oxygen-gtk" theme. More details are here. The proper solution is to change to a different theme, or upgrade/downgrade oxygen-gtk theme to a known-working version (1.4.2 should work).

Note that on July 18th, 2015 the bug was finally fixed by the KDE developers, however this will likely continue to be an issue until the patch lands in distro repos. More details are here.


Is there a portable version of Pale Moon for Linux?

A Windows "PortableApps" style application is not possible due to filesystem permission restrictions on Linux.

However, if you mean "portable" as in no installation needed, Pale Moon for Linux is already in such a state! Just grab the archive you want, extract it anywhere you like and run the "palemoon" file.

Will there be a package for $distro?

At this time there are no plans to provide packages for specific Linux distros. In most cases, the pminstaller tool can perform any needed installation, uninstallation and update functions.

However, Pale Moon has been made available for and is included in several distro's repos. See the main page for a list.

If you are interested in creating and maintaining packages for a specific distro, please let us know on the forum!

Pale Moon does not have an internal updater!

There is no internal updater built into Pale Moon for Linux at this time. This is by design:

  • The internal updater requires making mar archives and/or binary diffs, which is not done at this time, but is on the roadmap and we are going to look into it at some point.
  • Most users are likely to install it into /opt which is unreadable to most except the superuser, and running the browser as superuser is not considered proper security practice.

In the absence of an internal updater, the pminstaller tool can be used to update Pale Moon, or you can update manually.
