Chromebooks run on ChromeOS, which does not support certain kinds of web content like Java or Flash. Certain publishers' (McGraw-Hill or Pearson, for example) lab and textbook sites are not fully compatible with ChromeOS. The pop-ups that are blocked are attempting to install necessary plugins for the sites to fully function.
If you are having difficulty with your online courseware and/or online textbook, you should consider a laptop instead. It may meet your needs better. Please click the link below for more information about laptops.
