Hello, I have been using Firefox for so long, and it's one of my favorite web browser on Windows as well as on Android. Firefox update for Android has become frustrating for many people including me, as most of the features aren't available in this new FF. One of them is about:config system settings, where i use to change some usefull features by going through that option. Sadly, this isn't available in the new update as of now. So, I would like to request you that please add this option as soon as possible in the coming updates. Another request would be, to be able to change the dns within the browser for using secure dns like DoH. As this option is available in desktop browser, i will be happy to get this option even on Android as well. Thank you.....
