PSA when you update to Firefox 128 you might want to uncheck this
#Firefox
I expect that to be automatically disabled on Debian, but I will carefully double-check once Firefox 128 enters Debian repositories.
@vv221 @pixellight Debian’s overrides have not been working for some 70+ Firefox versions, and I reported the bug but nobody cared.
I don’t get it, here they seem to work nicely. Keeping in mind that I am using Firefox ESR from the Debian Sid repositories, not the regular non-ESR Firefox releases.

Do you have an URL to share to this bug report? Maybe I can reproduce that on one of my systems, and bump the report with more details.

#1031556 - firefox-esr: ignores /usr/share/firefox-esr entirely (e.g. search plugins, Debian prefs) - Debian Bug report logs

Thanks, now that I read that I remember that I get similar problems with the search engines.

On the other hand the telemetry disabling does work, it might be done through a compilation flag rather than a runtime preference.

@vv221 @pixellight must be so, also given the strace; this means all other overrides from there won’t work either though
