Desktop mode browsing is now enabled by default for large devices. This can be controlled via a preference under Settings in "Site settings" previously named "Site permissions".

The actual (desktop) Firefox for Windows, macOS, Linux is not available for Android. As said there is the desktop view mode in Firefox for Android.

However since the new uptate with Default Desktop mode; Causes still me lots of problems.

Since I have an Samsung Galaxy Tab S9FE ( SM-X516BEE).

The issues that I've experience is that the zoom function isn't as compatibel as expected. Since it more looks like an standard Desktop site. Even if I've try to zoom out as much as possibel.

So as I myself suspect, either that certain tablets from Samsung have compatibility issues( misstaken it as if it was Desktop mode)- or that the os gets confused and stucks in Desktop mode either way. But it also could be as simpel as when it was posted in Play store; that it was posted as Linux( for desktop). Since however Android is based on Linux( and only mirrored from an PC- version).

So out of my own personal knowledge it was better to skip this Desktop mode( by default).

However in previous versions ( before 130.0)- I've never experienced any of this issues( that the website looks more normal).

But however there are some incompatibel websites out there( but works fine on PC). But this is someting out of Firefox( Monzilla) control.
