# Pale Moon

Application: Moonchild Productions

Also called palemoon, pale moon browser

Moonchild Productions, Browsers

An independent Goanna browser that left the Firefox rapid train. On Windows the process is palemoon.exe.

## What you need to know

Pale Moon is Goanna. It is not Firefox.

Moonchild Productions ships palemoon.exe on Goanna. Stock Firefox is firefox.exe. Basilisk is a different XUL browser from the same team.

- **What is it?**: Web browser

  **Still current?**: Yes, see Current status

  **Official download?**: Use the vendor link in this article

Feex says

If palemoon.exe is running, I would not apply a Firefox Rapid Release fix. This is Goanna, not mozilla.org Firefox.

## What is Pale Moon?

Pale Moon is Moonchild Productions' independent desktop browser on the Goanna engine. The Windows executable is palemoon.exe.

## If you have never used it

If you want a browser that is not Firefox Rapid Release, this is Pale Moon. It uses the Goanna engine, not current Gecko. Download it from palemoon.org. The process is palemoon.exe. Firefox extensions from today often will not install. Basilisk is a sibling from the same team, not this exe.

## What is it used for?

**Goanna browsing**

Pages render in Goanna. Compatibility is not identical to current Firefox or Chrome.

**Older XUL-style extensions**

Pale Moon keeps a XUL-style add-on world. A current Firefox WebExtension may not apply.

**A non-rapid-release Firefox cousin**

You opted out of Mozilla's four-week train. That is the product pitch.

## Who is it for?

- People who still want Pale Moon add-ons
- Users who left Firefox Rapid Release on purpose
- Anyone who assumed palemoon.exe was firefox.exe

## Current status

Pale Moon (2009) is a current web browser from Moonchild Productions. The vendor still points Windows users at https://www.palemoon.org/.

## How old is it?

Pale Moon started in 2009 as a Firefox fork and later moved to Goanna. It dropped the Firefox rapid train on purpose. Current Pale Moon is not Firefox 1.0 and not a Chromium skin.

## Versions

Major channels first. Exact build numbers are not all verified here.

Current Windows build

## System requirements

Values follow the publisher's public guidance. Workload still changes the real need.

### Minimum

| Operating system | A current supported Windows 10 or Windows 11 release, per the vendor |
| ---------------- | -------------------------------------------------------------------- |
| RAM              | Enough for Windows plus this app. Heavy projects want more.          |

## Resource profile

- **CPU demand**: Follows what you open inside the app

  **RAM demand**: Follows documents, tabs, or libraries

## Installed processes

These executables belong to this product when it is installed.

| palemoon.exe | Main Windows executable |
| ------------ | ----------------------- |

## Startup components

Pale Moon can restore the last session. It is not a Windows service.

## File locations

| Typical install | C:\Program Files\Pale Moon\\ |
| --------------- | ---------------------------- |

## File formats

HTML, PDF, PNG, JPEG

## Common problems

### Modern sites expect current Gecko or Chromium

Some banks and SPAs break. That can be engine age, not a dead NIC.

### People install Firefox add-ons blindly

Current AMO WebExtensions often fail here. Use Pale Moon add-on sources the project names.

## Getting unstuck

### Confirm palemoon.exe under Pale Moon

firefox.exe is Firefox. basilisk.exe is Basilisk. This folder should say Pale Moon.

### Use palemoon.org/support

Release notes and add-on rules live with Moonchild. Mozilla Support will mislead you.

### Install only from palemoon.org

A Pale Moon plus toolbar pack is junk.

## Alternatives

Firefox if you want current Gecko. Basilisk if you want the other Moonchild XUL browser. Chrome if you need Chromium site compatibility.

A modest CPU is enough. Broken sites are often engine compatibility, not missing RAM.
