Mathxl is a (expensive) platform I need to use for homework but I can't get it to work. (It's a white screen) The stated system requirements include
Linux Ubuntu Firefox 46.0 to latest
Which should cover my Debian Firefox ESR. The software requirements are:
Adobe® Reader®
Wolfram® CDF Player
Adobe® Flash® Player
Java™ Runtime Environment
Third Party Cookie Check
Three are working (Flash w/ freshwrapper for pepperflash, java w/ iced tea, and cookies). Adobe Reader and Wolfram CDF aren't functional and I don't believe they need to be for me to do my homework. I can view PDFs without Adobe Reader and the description of Wolfram CDF "Allows you to view and explore the Interactive Figures and e-text of certain titles that were created using Mathematica®" makes me think it's not commonly used. Compare to Flash "Allows you to view the questions within the course. You won't be able to complete any questions if you don't install this component!". But I can't complete any questions. I've been trying to figure this out for hours but I must defer to the powers that be on SE because I have to get this homework done. I'll post from the source of the applet if necessary.
My specs:
Linux debian 3.16.0-4-amd64 #1 SMP Debian 3.16.36-1+deb8u2 (2016-10-19) x86_64 GNU/Linux
