Firefox and Mozilla
Cause 0 : since 27-SEP-2011, there is a bug in
addon.mozilla.org...The Windows version 0.910 is declared compatible at addon.mozilla.org with Firefox 7.0 but it is not.
No way for me to change this, it is all automatic... There is a bug logged for this.
Solution: Download the version 0.911 for Windows
or look the compatibility list
or wait that addon.mozilla.org solves the issue...
Cause 1: Operating system mismatch
This can happen when you have installed a version that is not for your
Operating system (OS). For example, installing the Linux version on
Windows or the opposite. The extension is available on Windows, MacOsX,
Linux 32bits, Linux 64bits and Linux PPC. This happens mostly due to
bad autodetection of the OS or caching issue in addons.mozilla.org.
Solution: re-install the extension for your OS.
- Please, look at the list of OS here, http://users.skynet.be/mgueury/mozilla/download.html and
install the version for your OS. Take care to allow this site to
install an extension (green toolbar at the top)
- Retry in addons.mozilla.org and take care that the
installed is the one for your OS.
A. On linux, depending of your linux distribution, it can be that the
standard C++ libraries installed on your distribution are not the one
linked with the extension. To correct this, please read the detailed
Take also care that the extension is different for Linux 32bits (most
common), Linux 64bits and Linux PPC.
B. In an update on Debian
from about June/July 2006, solved in about August 2006. The extension
does not work on Debian
anymore. The reason is the way debian has changed his way to link the
XPCOM library in Firefox.
You need to be administrator to install the extension on Firefox in
When reinstalling a new version of Seamonkey on an existing one,
Seamonkey warns that it will deregister all components. Practically,
the library of the extension is deinstalled. To solve this, just
reinstall the extension. Download
Browser (Netscape 7.x, 8,x, Seamonkey 1.0.x)
Like told in the download area, the extension has been tested
on Firefox, Mozilla Suite 1.7.
It is reported to work on Flock without any issue.
It does not work on Seamonkey, nor on Netscape 7.x or 8.x.
If you use these browser please deinstall the extension. See below.
