"official" versus "unofficial" linux builds: different user agents

Post by Walter Dnes » 2024-10-23, 18:02

This is NOT a support request, but rather a report of an anomaly in the build preocess.

Step 1) Linux build with .mozconfig as per https://developer.palemoon.org/build/linux/
Step 2) After build, go to URL https://www.youtube.com/watch?v=R1AsPwvySbA&t=658s
It runs fine, including chat replay.

VERSUS

Step 1) Make 2 changes to .mozconfig for linux build

ac_add_options --disable-official-branding
export MOZILLA_OFFICIAL=0

Step 2) After build, go to URL https://www.youtube.com/watch?v=R1AsPwvySbA&t=658s
The video runs, but chat complains about older version of browser (see attachment).

I compared user agents at https://www.whatismybrowser.com/detect/ ... ser-agent/
The "official build" that works reports user agent...
Mozilla/5.0 (X11; Linux x86_64; rv:102.0) Gecko/20100101 Goanna/6.7 Firefox/102.0 PaleMoon/33.4.0.1

The "unofficial build" that fails reports user agent...
Mozilla/5.0 (X11; Linux x86_64; rv:6.7) Goanna/20241023 PaleMoon/33.4.0.1

After some experimentation, I created "general.useragent.override.youtube.com" and had to set it to

Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:83.0) Gecko/20100101 Firefox/83.0

Yes, unofficial does not default to Firefox Compatibility for the UA. It uses Native instead, which is the platform default.

Just to clarify:
Some webmasters use the User Agent header to determine if their website "works" in a browser or not.
As MC pointed out, the default UA is different without the branding, this explains the result.

So I did some comparisons again at https://www.whatismybrowser.com/detect/ ... ser-agent/ Under "Tools ==> Preferences ==> Advanced ==> Compatibility" is a drop-down menu with 3 options...

==> Native
Mozilla/5.0 (X11; Linux x86_64; rv:6.7) Goanna/20241010 PaleMoon/33.4.0.1

==> Gecko
Mozilla/5.0 (X11; Linux x86_64; rv:102.0) Gecko/20100101 Goanna/6.7 PaleMoon/33.4.0.1

==> Firefox
Mozilla/5.0 (X11; Linux x86_64; rv:102.0) Gecko/20100101 Goanna/6.7 Firefox/102.0 PaleMoon/33.4.0.1
