I have had several changes in the parameters to Firefox that I did not make. The first was the home content was changed from none selected to "recommended by pocket" being activated The second was the option was "firefox updates" I have mine configured to "Check for updates but let you choose to install them" but this was overridden when a new version occurred and Firefox updated it self despite the setting. The third occurrence was the newly added "custom" field added to the "Enable DNS over HTTPS" even though I placed a forum request asking for a definition for this new parameter and I have not yet received a response, it was selected causing DOH to stop functioning. These changes did not occur at the same time but separately. I would be interested in knowing any theories as to why this has occurred?
