I recently downloaded the ISO image for a Knoppix Live CD so I could test my DSL line with a second OS (supposedly a better OS) to narrow my speed problems to software or hardware without having to reformat my HDD. I'm trying to use one of many java based speed tests, all of which require a firefox plug in. How do I install the plugin with a Live CD, and is there a way to add it to the ISO image and burn another CD so I won't have to add the plug in every time I boot off the CD?
