I am using the latest version of firefox and every single time I complete a portion of the challenges it loads the next page, but then in the code window is messed up. It is sized beyond the bottom of the page, I can’t click all the way to the end of lines and edit them. A change and window size fixes it, but then it happens immediately again upon going on to the next step. It is pretty annoying to be trying to write code in your window and have it keep needing to be resized.
I haven’t opened the console to try and debug the code and try and figure out what is broken; I could I suppose. I would prefer not to be forced into using another browser. I mean that pretty much goes against everything I have learned during my limited time doing webdev anyway, code should work in pretty much all modern browsers.
