I logged into my Firefox account and then tried to load about config and I got the java script error message. Wouldit help to uninstall Firefox and then reinstall it or what?
Additional System Details
- User Agent: Mozilla/5.0 (Android 8.1.0; Mobile; rv:68.0) Gecko/68.0 Firefox/68.0
Why would you want to mess with about:config settings in the first place?
