Known issues in the current version
The Pale Moon browser, at any point in time, may have a number of known
issues. These known issues will usually be addressed in the next
release of the browser, or it may be something that people have noticed
and are mentioned here because they are "by design", i.e.: issues
people have asked about, are known, and are this way on purpose.
For each issue, check the status for intended action to be taken in
development (if any) and intended timeline (if applicable).
Known issues in 24.4.2:
- On some sites, the plugin notification icon may incorrectly show or provide a blank doorhanger
This is caused by page content removing document nodes and confusing
the plugin indicator code. As a result, you will see the following when
clicking the plugin indicator:
Timeline: Fixed in the next release
rendering of text and graphics may become "pixelated"
If you are using Windows 7 SP1 with the (Feb 28th
2013) Windows Platform Update (KB 2670838), or
potentially also if you are using Windows 8/8.1, and your system is
equipped with a certain legacy ATI/AMD Radeon (specifically an HD3000 or HD4000 series) graphics
processor, you may encounter issues with rendering text and graphics in
page content, similar to:
is caused by the combination of OS, the Platform Update which
makes changes to DirectX, and the graphics
hardware/drivers in your system. Unfortunately, it's not clear who
exactly is to blame, as people keep pointing fingers to others
(Microsoft, AMD, Mozilla). Note that it may also have been installed as
a prerequisite for using MSIE
Of note: Later versions of Pale Moon are less likely to display this error than Firefox, but it may still occur.
Workaround: See http://forum.palemoon.org/viewtopic.php?f=1&t=2228
- TL;DR: uninstall KB2670838 or disable azure for content.
Status: [Use workaround]
Known issues in the 3.6.*
versions (Legacy, discontinued):
Known issues in all versions:
sites render particularly slow or stall the browser, or don't display
This is caused by the websites in question using more modern website
coding, notably more advanced HTML5 and CSS3, that is not and will not
be supported by the Legacy version of Pale Moon (the Gecko rendering
engine used in this version does not properly support it).
Solution: Upgrade to
the Next Generation version of Pale Moon
(if your hardware and O.S. support it).
Status: [Inherent, won't fix]
browser creates directories under %APPDATA%\Mozilla, specifically
These directories are related to the underlying Mozilla extension code (Pale Moon is a Mozilla-based browser)
and stores extension IDs there. This issue is completely harmless and
non-breaking; in fact, having (all) Mozilla-based applications use this
one central location for extension IDs is desired.
Status: [By Design]
Known issues in previous versions
Because issues in previous versions may still apply to what people are
running, here is a recap of previous, still recent versions that have been fixed, and potential workarounds:
- The download manager panel may pop up in the far bottom-left
On some installations, the download manager panel may possibly pop up
on the bottom left of the browser instead of where the download manager
button is. This is caused by a small issue in the default set of
controls in the v24.4.0 updated status bar code, confusing the panel by
having 2 places to "hang" the panel from.
I will be fixing this by removing the status bar download control from
the "default" set of controls (like in previous versions).
Workaround: Open the
customization window (right-click a toolbar button and select
Customize... from the menu) and remove the download manager control you
don't intend to use (either the button in the main navigation bar or
the control in the status bar) by dragging it from the browser window
to the customization window.
Timeline: Fixed in 24.4.2.
- Trying to open up the download manager from the download status control doesn't work
Trying to open up the download manager (either panel or classic window)
by clicking on the status bar control for downloads does nothing. This
is caused by a small issue in the newly updated status bar code in
Timeline: Fixed in 24.4.1
- When using the classic downloads window, downloads in private windows are not shown
If you use the classic downloads window and open a Private Browsing
(PB) window, there is no easy way to see which downloads are done in
the PB window. When checking the downloads, it will open up the
(non-PB) classic downloads window which does not have downloads listed
from the PB session.
This is caused by PB windows being implemented after Mozilla moved to
the panel-based downloads manager, and there is no check in the classic
downloads window if it is called from a PB window or regular window.
Workaround: In the PB window, open a new tab and type about:downloads in the address bar
Timeline: Fixed in 24.3.0
- Geolocation doesn't work in Pale Moon
This is caused by the Firefox standard geolocation provider (Google
Inc.) now requiring an API key to request geolocation coordinates. Only
official Mozilla Firefox builds of the code will work.
Pale Moon will be switching provider to address this issue.
Timeline: Fixed in 24.3.0
- The "More information" link for blocked add-ons doesn't work
Workaround: See http://forum.palemoon.org/viewtopic.php?f=29&t=2750
