<caution>

<para>
|
|
If you are upgrading JS78 from a previously installed old version,
|
|
save all work and exit your GNOME Session if you have one running.
|
|
Replacing the JS78 binary will cause the GNOME Shell to crash and
|
|
return you to your display manager or TTY. After installing the new
|
|
version, if GNOME Shell still doesn't work, reinstall
|
|
<xref linkend="gjs"/>.
|
|
</para>
|
|
</caution>
|
|
|
|
<note>
|
|
<para>
|
|
Unlike most other packages in BLFS, the instructions below require you
|
|
to untar <filename>firefox-&ff78-version;esr.tar.xz</filename> and
|
|
change into the <filename>firefox-&ff78-version;</filename> folder.
|
|
</para>

<para>
|
|
Extracting the tarball
|
|
will reset the permissions of the current directory to 0755 if you
|
|
have permission to do that. If you do this in a directory where
|
|
the sticky bit is set, such
|
|
as <filename class="directory">/tmp</filename> it will end with error
|
|
messages:
|
|
</para>
|
|
|
|
<literallayout>tar: .: Cannot utime: Operation not permitted

tar: .: Cannot change mode to rwxr-xr-t: Operation not permitted

tar: Exiting with failure status due to previous errors
|

</literallayout>
|
|
|
|
<para>
|
|
This does finish with non-zero status, but it does
|
|
<emphasis>NOT</emphasis> mean there is a real problem.
|
|
Do not untar as the <systemitem class="username">root</systemitem> user
|
|
in a directory where the sticky bit is set - that will unset it.
