Hi , you may want to update your Video Card Drives as noticed a couple errors in the info that came with you. This will detect your card/chip : https://www.intel.com/content/www/us/en/support/detect.html Quickfox Notes is not a part of Mozilla and with this new Engine and code the Developers decided that they could not make the changes needed or access was no longer there for security reasons. You could Contact the Developer to ask if there is any way to pull the information out in a usable form or: Going back : unfortunately 56.0.2 is no longer safe to use for every day use, but 52.5.0 ESR is! It will continue to get security updates until May 2018, and you can download and install it from this page: https://www.mozilla.org/en-US/firefox/organizations/all/ Do not run 2 Firefox's as they will conflict. You can run the Developers Edition https://www.mozilla.org/en-US/firefox/developer/ and the other as there is a compatibility mode at the end of the install. Please let us know if this solved your issue or if need further assistance.
