Firefox fails: Responsive design mode

I want to use Firefox. I really want to, because after Opera ditched its own rendering engine and started to use Chrome's Blink engine in 2013, Firefox was the only real competitor to Chrome - and Chrome is a cornerstone in the Google Monopoly Builder program. ​

But Mozilla makes it hard to love Firefox: ​

Responsive Design Mode​

So because I want to use Firefox, I also try to use it for website development. ​

I opened a website on my phone, and it looked bad - much too small. To fix that, I used Firefox' Responsive Design Mode to test it, but it rendered completely different than the phone. ​

Here is the comparison how Chrome (Chromium) render the same page: ​

Mobile view mode: Firefox vs. Chrome ​

Firefox does it wrong, Chrome does it right. ​

In the end the problem is that Firefox does not care that the viewport meta tag is missing (since 2016), but as developer I do not want to know about that "special behavior" in Firefox. I want it to work, but Mozilla rather pours money into their own now-ditched Mobile Operating System "Firefox OS" and other shit, than to fix bugs that prevent people from using their browser for work. ​

A big long sigh. ​
