Pale Moon is designed to take advantage of hardware features any
reasonably modern desktop computer should have. As such, it is built to
use broadly-present CPU features, and works best with graphics cards
that have good acceleration support.
Minimum requirements for
- A processor with at least SSE2 support (any CPU that is not
museum-grade should be fine).
- We only support 32-bit on Windows. All other operating
systems require 64-bit.
- At least 2 GB of free RAM.
While it may be possible to run it in limited fashion on less RAM, it
isn't recommended as memory pressure will cause a lot of performance
loss and may cause crashes.
- A reasonable screen size (720p or higher).
- A 64-bit processor and O.S.
- 4 GB of free RAM.
- A dedicated GPU with stable driver support.
System requirements when running on Microsoft Windows:
- Windows 7 with service pack 1 or later. We do not support
Vista or Windows XP.
- All applicable security updates installed.
- At least 150 MB of free drive space for installation. More
recommended for caching and profile data.
Pale Moon is specifically optimized for current-day processors
and as such requires a reasonably modern system to run properly. See
also hardware requirements above. Especially for Linux, often used on
very old hardware, this is a point of note.
NOTE: Linux 32 bit binaries have been
discontinued. However, your distribution (or one of the fantastic
package contributors) may still offer 32 bit packages at their
discretion. If they do you should remove the "generic" binary and
install said package. Otherwise, to continue using the Pale Moon
binaries we distribute, please update to a 64 bit distribution of your
- A modern Linux distribution. The browser may not work well
on old or LTS releases of Linux.
- 2GB of RAM (4GB or more recommended for heavy use).
- GTK 2.24 or GTK 3.22+, depending on which version you
download. GTK4 is not supported.
- GLib 2.22 or higher
- Pango 1.14 or higher
- libstdc++ 4.6.1 or higher
An Intel 64-bit or Apple Silicon Mac running MacOS X 10.7 or later.
Our support for FreeBSD will be for the Legacy, Production and Upcoming
trees. i.e. if the Legacy branch is 12, then FreeBSD 12 or later is
required and 11 or before is unsupported. When version 14 will be
Production and 13 will become Legacy, as 15 will be created as the new
Upcoming tree, we'll start building with a minimum of 13 and 12 or
before will be
out of support.
- A 64-bit Intel machine and 64-bit FreeBSD.
- GTK 2 or 3 package installed.
- ALSA package installed.
