I SOLVED FROM MYSELF IT: https://github.com/nextcloud/spreed/issues/3323 here is the solution

The problem seems to be Firefoxes resistFingerprinting flag.

If you go to about:config in Firefox, and set the flag privacy.resistFingerprinting to true, the issue arises. ✔️ Solution

You can use fingerprinting protection with an exception for AudioContext:

privacy.fingerprintingProtection = true 
privacy.fingerprintingProtection.overrides = +AllTargets,-AudioContext

If a site is broken by fingerprinting protection, you can disable Tracking Protection for the site.

I found that with this settings does not work inline copy and paste of immages inside web whatsup but works inside facebook chat. So or voice messages or immages inside whatsup hmmmmmm

I even tried with privacy.fingerprintingProtection.overrides = +AllTargets,-AudioContext but whatsup still not work if I change privacy.fingerprintingProtection = true

unable to find Report a broken site inside browser, I followed guide but not found where to report facebook.

hmmm as not said for whatsup, done more checks and photos are posted well , only immages captured from LIGHTSHOT app https://app.prntscr.com

as 17 april 2024 new version 125.0.1 has been applied I tried to remove customizations as here solved and continue to work fine even without privacy.fingerprintingProtection = true

In all case I see no configurability on this new system and even can't be put OFF.

I find this really not good in a spread world of computers and needs.

Things like this let users to move to other browsers.

please adjust visibility and configurability on privacy.fingerprintingProtection
