General

Pale Moon does not work on my computer!

If Pale Moon refuses to work try starting it from the terminal and see what error messages are displayed. If you are not able to resolve the message that is provided, it is recommended you post the problem and error message(s) on the forum.

The internal updater is not working!

Pale Moon ships with its own internal updater. However, in order for the updater to work properly Pale Moon must be extracted to a user-writable location. If the updater is reporting an update available but is not updating, please ensure that the "palemoon" directory is writable by your user account.

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.

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.

Extensions

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

More details on extension compatibility can be found here.

Problems

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

  • If the icon does not appear, try updating 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.

Miscellaneous

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. However, Pale Moon has been packaged for some specific distros by 3rd party maintainers and is included in several distro's repos. See the main page for an officially endorsed list.
