... normally I am able to zoom browser (firefox) tab using "Ctrl" + "+" shortcut, but in case of this "terminal" browser - all keyboard input is directed to the terminal so the shortuct takes no effect.
... I tried that now in RHU course lab and there is the same issue. Even if I zoomed in the "terminal" page using Firefox menu "Zoom" option, terminal font is still tiny. See the attachement.
I've experineced the same issue , fonts are small and not sharp even if i zoom in the browser and termianal. Also it was very slow (my internet connection is super fast), and copy paste didn't worked from the exam browser to the terminal and that's the real deal breaker. I worked on the exam until the last minute , and usually i complete the tasks ealry.
Because of this i return to test location with redhat laptop , for me it's the best and safe option.
