This is a quote from Klaus: "sudo apt install -t unstable chromium sudo apt install -t unstable firefox[-esr] If you are looking for security-related updates, you can also do update-security" while you are in the same release (now 8.6.x). I updated my browser twice already and the first time Chromium kept crashing after 5 minutes or so, which was solved with the second update. Now, why knoppix? The same reason Klaus uses it: keep desktop, network credentials, browser cookies, and encrypted information wherever you can go with a USB memory. I have Debian installed in my computer. And, even though this question was made ages ago, it still shows in the search, and needed some response, imo.
