"Create a Media Query" not working on Firefox

Tell us what’s happening:
As of 17 August 2021, the code below did not function properly on Firefox, but went through when swapping to Chrome. FWIW: I was using a second monitor with a different resolution than my laptop screen, but this has never caused an issue (for me) before. No idea if Firefox is maybe behind on CSS3?

I thought I had the code right, and even went so far as to literally copy and paste the code from the solution found elsewhere, and it still did not work despite multiple resets until I switched to Chrome, which got it to work on the first time.

  **Your code so far**

p {
  font-size: 20px;

/* Only change code below this line */
@media (max-height: 800px) {
  p {
    font-size: 10px;
/* Only change code above this line */

Challenge: Create a Media Query

Link to the challenge:

At the beginning of the RWD course is the following:
Note: Some browser extensions, such as ad-blockers and dark mode extensions can interfere with the tests. If you face issues, we recommend disabling extensions that modify the content or layout of pages, while taking the course.

Other things to consider;
browser is at current, stable release
cache cleared when something should pass but does not


Media queries use max-width as a parameter, not max-height. Kindly check your parameter and try again.

I hope this helps
