the brave brwoser is very faste,

but not favorite taste.

the firefox - nightly function well but some sites don't load or video not play

like here

_https://www.corriere.it/esteri/25_novembre_12/trump-bbc-causa-risarcimento-26424e0b-eb2a-4f6b-84a4-0740efafexlk.shtml (embedded video not play)
_https://www.dailymotion.com/Corriere-della-Sera?sort=visited (site not load)

both links would function on firefox-esr.

Try Speedometer with Brave browser

Audacious and Audacity are different applications, despite their similar names. Audacious is a lightweight and versatile audio player designed for POSIX-compatible Unix-like operating systems, with limited support for Microsoft Windows, and it is known for its support of Winamp skins and a media library. It began as a fork of Beep Media Player, which itself is a fork of XMMS.
On the other hand, Audacity is an audio editor used for recording, editing, and producing audio files, supporting a wide range of audio formats and offering features like noise reduction and time-stretching.
While both are free and open-source software with similar licensing (GNU General Public License v3.0 or later), they serve distinct purposes: Audacious for playback and Audacity for audio editing.
The confusion between the two is common, but they are separate projects with different development histories and functionalities.

There are many reasons to compile Audacious.
Most important, you can learn how to compile and make Debian packages.
You can also learn how to calculate dependencies.

You can compile Audacious (and plugins) with meson and ninja
1. Setup the build system
arch-meson audacious build 
2. Compile
meson compile -C build
3. Install to debdir
meson install -C build --destdir "$(dirname $(pwd))"/debdir

Ninja is almost invisible, as the name suggest. For example:

$ meson compile -C build
INFO: autodetecting backend as ninja
INFO: calculating backend command to run: /usr/bin/ninja -C /home/.../Audacious-git/Builds/build
ninja: Entering directory `/home/.../Audacious-git/Builds/build'
[171/171] Linking target src/audacious/audacious

$ cat arch-meson
#!/bin/bash -ex
# Meson wrapper for Arch Linux packaging

exec meson setup \
  --prefix         /usr \
  --libdir         /usr/lib \
  --libexecdir     /usr/lib \
  --bindir         /usr/bin \
  --sbindir        /usr/bin \
  --includedir     /usr/include \
  --datadir        /usr/share \
  --mandir         /usr/share/man \
  --infodir        /usr/share/info \
  --localedir      /usr/share/locale \
  --sysconfdir     /etc \
  --localstatedir  /var \
  --sharedstatedir /var/lib \
  --buildtype      release \
  --wrap-mode      nofallback \
  "$@" \

dummy@example.com (kapqa) — Mon, 20 Oct 2025 20:03:31 +0000

will check with the extensions , but the firefox is sufficiently fluid for me, not slow at atll;
yes, since few weeks use (mozilla acocount sync) so make it easy for them to track me.
but it should nopt slow that much.

also, the benchmark is bit unfair , between mint and ubuntu snap (ubuntu probably heavily tweaked).
the benchmark was from here , with nightly around result 20, with snap version is lot higher
https://browserbench.org/Speedometer3.1/

thanks for the help with linux,
will see what i can contribute;

have just yesterday or other day installed audacity on old powermac g5, it is nice program, but why would you want me to compile it? it is easy to install via pacakge manager?

best of wishes.

What do mean by "performance-hit"?

about:processes Task Manager - see whether tabs or extensions are slowing down Firefox
_https://support.mozilla.org/en-US/kb/task-manager-tabs-or-extensions-are-slowing-firefox

apulse firefox

apulse is not needed because your Firefox does not have "pulse-rust" backend.
It does not make any harm, but you may better remove it from your Firefox launcher.

$ file /usr/bin/firefox-nightly
/usr/bin/firefox-nightly: symbolic link to /usr/lib/firefox-nightly/firefox-nightly

dummy@example.com (kapqa) — Mon, 20 Oct 2025 17:32:53 +0000

dear igor,

found the .debdir instruictions fuzzy, so just went a lazy way and copied the files over
like so

sudo cp -a usr/. /usr/

and for the firefox.desktop adapted a oneliner from antix-forum

cat /usr/share/applications/firefox.desktop |sed "s/Exec=.*/Exec=apulse firefox %u/ig" > ~/.local/share/applications/firefox.desktop && sudo desktop-menu --write-out-globalcat /usr/share/applications/firefox.desktop |sed "s/Exec=.*/Exec=apulse firefox %u/ig" > ~/.local/share/applications/firefox.desktop && sudo desktop-menu --write-out-global

where adapted to nightly seemed to function just fine.

the browser function well so far;
however benchmark wants to tell me have lost 50% performance when compared to snap-version
but for better audio, am glad to take the performance-hit.

The Last Cargo Cult Interviews
_https://www.youtube.com/watch?v=YB-26XqDZj8
_https://youtu.be/YB-26XqDZj8
Dec 3, 2009
In THE LAST CARGO CULT, groundbreaking monologist Mike Daisey (If You See Something Say Something) returns to The Public with the story of his journey to a remote South Pacific island whose people worship America and its cargo. This narrative is woven against a searing examination of the international financial crisis that gripped the globe at the same moment. Confronting the financial system that dominates our world, Daisey wrestles with the largest questions of what the collapse means, and what it can tell us about our deepest values. Part adventure story and part memoir, he explores each culture to unearth a human truth between the seemingly primitive and achingly modern.

Native cargo cultists could easily imagine cargo planes because they had witnessed the arrival of real military aircraft during World War II, which delivered supplies and goods seemingly from the sky.

It should not be difficult, therefore, to imagine a Devuan wiki with all the knowledge you need.

Native cargo cultists typically obtain their knowledge of "the true secret of cargo" through dreams or visions, which are considered revelations from ancestral spirits or deities. These prophetic experiences are central to the formation of cargo cults, as a charismatic leader often claims to have received a vision or "myth-dream" that foretells the return of ancestors or a messianic figure who will bring abundant goods... The dream or vision legitimizes the leader's authority and serves as the foundation for the movement's rituals and expectations.

You may also try to read a secret Devuan wiki in your dreams.

It may fail on very old computers.

    --disable-tests           Do not build test libraries & programs
    --enable-release          Build with more conservative, release engineering-oriented options. This may slow down builds.

We relish talking about cargo cults because we can imagine ourselves as cargo cultists. Besides, the fact that we are the real cargo cultists is no longer latent or suppressed. Nowadays, so we say, we find that the cargo cult more and more is erupting in the West.

Firefox Nightly is quasi portable. You can make a Debian package for Firefox Nightly on Devuan and install it on Linux Mint (and other way round).

You can build the fftrate Debian packages on Devuan, or Linux Mint, or Ubuntu, and install them on other Debian based distros.

But the Raspberry Pi is based on the ARM architecture, you may try to build the fftrate plugin on Raspberry Pi.

hello igorzxx, it is funny with you
yes, i chose "1" articfacts, but it would not fail.

now will select "2" and learn to behave.

or even better, will remove kubuntu and check for devuan 6 or linux mint (again: ubuntu?)

thanks for educating me, very much appreciated.

Re: How to disable pulse-rust backend in Firefox

dummy@example.com (igorzwx) — Fri, 17 Oct 2025 14:02:56 +0000

@kapqa

Your build failed, because pre-built Artifacts are not supposed to be modified and recompiled.

You installed the wrong thing, because ...
because you are always trying to minimize "thinking and making".

Just as muscles degrade from disuse, the brain also degrades if it is not stimulated or "trained". The brain is not a muscle, but it functions on a similar "use it or lose it" principle, where a lack of activity leads to a loss of function and neural pathways. Training the brain, like exercising the body, strengthens its neural connections, improving cognitive function and protecting against decline and progressive dementia.

Dementia is always progressive.

_https://firefox-source-docs.mozilla.org/setup/linux_build.html
Choosing a build type
If you aren’t modifying the Firefox backend, then select one of the Artifact Mode options.

You should select 2. Firefox for Desktop

Note on Artifact Mode:

Artifact builds download prebuilt C++ components rather than building
them locally. Artifact builds are faster!

Artifact builds are recommended for people working on Firefox or
Firefox for Android frontends, or the GeckoView Java API. They are unsuitable
for those working on C++ code. For more information see:
https://firefox-source-docs.mozilla.org/contributing/build/artifact_builds.html.

Please choose the version of Firefox you want to build (see note above):
  1. Firefox for Desktop Artifact Mode [default]
  2. Firefox for Desktop
  3. GeckoView/Firefox for Android Artifact Mode
  4. GeckoView/Firefox for Android
  5. SpiderMonkey JavaScript engine
Your choice: 2

You have to start from the very beginning
1. Create a new folder
2. Download bootstrap.py
and so on

_https://firefox-source-docs.mozilla.org/setup/linux_build.html
2. Bootstrap a copy of the Firefox source code
Now that your system is ready, we can download the source code and have Firefox automatically download the other dependencies it needs. The below command will download a lot of data (years of Firefox history!) then guide you through the interactive setup process.
curl -LO https://raw.githubusercontent.com/mozilla-firefox/firefox/refs/heads/main/python/mozboot/bin/bootstrap.py

python3 bootstrap.py

Edit:

It is very probable that the same pre-built Artifact will be automatically downloaded.
The easiest way to fix the problem is to remove your Ubuntu together with KDE and pipewire

Is it so difficult to save a copy of terminal output?

The following directory will be created:

  /home/rich/.mozbuild

If you would like to use a different directory, rename or move it to your
desired location, and set the MOZBUILD_STATE_PATH environment variable
accordingly.
