Conditions
System: Linux Fedora fc20.x86_64, CPU i520M, 3.66 GiB RAM on DELL E5410
Libraries have been updated from rpm packages of Fedora distribution fc21.x86_64
to satisfy the requirements for Firefox 128 and now following
versions of relevant libraries and packages are installed:
X.Org 1.14.4, libstdc++ 4.8.3, glibc 2.18, libglib 2.42.1, GTK+ 3.14.5
NetworkManager-0.9.9.0, dbus-1.6.30, GNOME 3.10.0, PulseAudio 5.0
Updating to newer version of Fedora is not possible option for me now.
Firefox 128.0.3 tarball has been unpacked to /usr/local/lib64/firefox128
Executable bash script, /usr/local/bin/firefox128
has been used to launch Firefox 128, it contains two lines
export LD_LIBRARY_PATH=/usr/local/lib64/firefox128:$LD_LIBRARY_PATH
/usr/local/lib64/firefox128/firefox $1
Existing file $HOME/.mozilla has been temporarily renamed to avoid
hardly possible conflicts while testing the new version of Firefox.
(Later I have found that this is not necessary because new installs
of Firefox do not conflict with the previous).
Problem
Execution of the bash script, firefox128 from gnome-terminal command line
started Firefox 128 but without GUI. Only the small white interval at left
upper corner of the desktop appeared and it could be extended by using mouse
to empty (white) window created by Gnome and titled, Firefox.
Observations
After Firefox 128.0.3 started the output of the command, ps -flu username
revealed,
/usr/local/lib64/firefox128/firefox
/usr/local/lib64/firefox128/firefox-bin \
-contentproc -parentBuildID 20240725162350 \
-prefsLen 21615 -prefMapSize 245327 \
-appDir /usr/local/lib64/firefox128/browser \
{d54171b1-8a79-44b3-a271-db4e09db2365} 3715 true socket
Two parameters preceding `true socket` vary from launch to launch.
Executions of, firefox128 --help
firefox128 --full-version
display the expected output
In the way of successive approximations to highest Firefox version that
starts with GUI in my system I have found this is Firefox 95.0.2
The binaries firefox in Firefox versions from 96.0 to 99.0.1
do not launch firefox-bin and the application hangs requiring explicit kill
Firefox versions 100.0.2, 101.0, 106.0, 106.0.5, 117.0, 117.0.1, 123.0.1, 128.0
I have tested like Firefox 128.0.3 behave in the same way as Firefox 128.0.3
with the same effects.
Output of the command, ps -flu username
obtained when
Firefox 95.0.2 is running with GUI in my system differs specifically from
outputs of this command for Firefox versions above 100
Last argument for firefox-bin in those Firefox versions i.e. 100.0.2 and newer
is `socket` whereas in Firefox 95.0.2 the last argument is `tab`
as in the case,
/usr/local/lib64/firefox95/firefox-bin \
-contentproc -childID 2 -isForBrowser \
-prefsLen 4814 -prefMapSize 241644 -jsInitLen 278884 \
-parentBuildID 20211218203254 \
-appDir /usr/local/lib64/firefox95/browser 9563 true tab
/usr/local/lib64/firefox95/firefox-bin \
-contentproc -childID 6 -isForBrowser \
-prefsLen 5627 -prefMapSize 241644 -jsInitLen 278884 \
-parentBuildID 20211218203254 \
-appDir /usr/local/lib64/firefox95/browser 9563 true tab
/usr/local/lib64/firefox95/firefox-bin \
-contentproc -childID 7 -isForBrowser -prefsLen 5627 \
-prefMapSize 241644 -jsInitLen 278884 \
-parentBuildID 20211218203254 \
-appDir /usr/local/lib64/firefox95/browser 9563 true tab
During executing both the bash scripts firefox128 and firefox95, launching
the respective Firefox versions, Firefox writes messages to stdout (gnome-display)
but the outputs do not differ qualitatively.
For firefox128 the only intriguing mesasage is the last one that appears
while closing Firefox 128,
[GFX1-]: RenderCompositorSWGL failed mapping default framebuffer, no dt
These messages not differing qualitatively for Firefox 95.0.2 and Firefox 128
can be summarized as follws
(firefox:5370): Gtk-CRITICAL **:
gtk_widget_get_style_context: assertion 'GTK_IS_WIDGET (widget)' failed
gtk_style_context_get_state: assertion 'GTK_IS_STYLE_CONTEXT (context)' failed
gtk_style_context_get_property: assertion 'GTK_IS_STYLE_CONTEXT (context)' failed
gtk_style_context_get_background_color: assertion 'GTK_IS_STYLE_CONTEXT (context)' failed
gtk_style_context_get_color: assertion 'GTK_IS_STYLE_CONTEXT (context)' failed
(firefox:5370): GLib-GObject-CRITICAL **: \
g_value_unset: assertion 'G_IS_VALUE (value)' failed
(firefox:2901): GLib-GObject-CRITICAL **: \
g_object_ref: assertion 'object->ref_count > 0' failed
and
g_object_unref: assertion 'object->ref_count > 0' failed
[GFX1-]: glxtest: libEGL missing methods
For Firefox 128 they are preceded by warnings like,
[Parent 4185, Main Thread] WARNING: \
g_value_unset: assertion 'G_IS_VALUE (value)' failed: \
'glib warning', file /builds/worker/checkouts/gecko/toolkit/xre/nsSigHandlers.cpp:187
Moreover during starting Firefox in versions 96.0 - 117.0.1
there is the message,
os_mmap failed.: Cannot allocate memory
This message is absent
either in Firefox 95.0.2 and Firefox 128.0, 128.0.3
Motivation
The effect just described looks very strange but may be common to older versions
of Linux distributions still being used by number of people with various motivations.
Various institutions, particularly banks, require "newest" versions of a browser
and I am afraid that Firefox 95.0.2 working in my system will be very soon considered
outdated that will result in lack of electronic access to bank account.
Therefore solving the problem just presented appears to be important.
Thank you in advance
