Moon unstable releases
versions of Pale Moon are built somewhat regularly from the current
development source of the browser and should only be considered for use
by people who wish to help catch bugs before release.
The unstable versions of Pale Moon come with recognizable
unstable branding (a "blood moon") to clearly indicate its difference
from the official releases.
Make sure you make regular backups of your Pale Moon profile as
unstable versions may occasionally cause data loss. Unstable versions
do not use a separate user profile, so if you decide to use
release-version profile will be used and potentially be at risk.
Release notesYou can find some concise release notes about this development version here:
If you find bugs in these versions, please report them in the issue tracker
on GitHub for Pale Moon. When you do so, please check if the bug has
already been reported before by others to prevent duplicate
the tracker. If you report bugs, make sure to include the build date
(as found in the about box) and provide clear information about the bug:
Also make sure that before you report a bug, that you verify if the bug
also manifests with default
preferences and no installed
(preferably create a new profile to check).
- Clear description of the bug found, with a concise and
clear title for the issue
(include exact circumstances and exact error messages, if any)
- Steps to reproduce
(what exactly do you do to cause the bug to become apparent?)
- Expected results
(given the steps taken, what did you expect the browser to do?)
- Actual results
(what did the browser do instead of what was expected?)
The unstable versions have their own update channel, separate from
official releases. The preferred way of updating is to let the internal
updater do its task (default setting is to update automatically).
These versions are only available in 32-bit for Windows. They are
not cryptographically signed due to the Release Engineering overhead
involved in such things.
