Firefox Android on an older Sony Xperia Android Tab (2016) still receiving Firefox updates, would you believe it, cannot access about:config page -- and yes it's about:config I'm attempting to access. Firefox adress bar icon displays site warning and freezes the page load whatever setting i try in Firefox settings.

No antimalware or such nonsense used on the device, just as fake in protecting my privacy as (foreign) gov.-sponsored whitelabel antimalware and privacy search engines -- remembering the recent Bing API-blackout that displayed a Bing search engine error message in all of the so called's etc etc

I'm not logged in on the device, as in not syncing an access all home living room device in any way. I don't need a breadcrum trail of other users leading to my accounts.

So what am I after? I don't want a stored cache of recently visited pages that apparently hog the limited memory and I want to limit the amount of 'recently visited pages'-cache stored in Firefox on Android. I want Firefox to be *pristine (beyond the moniker settings available as 'clear all' at Firefox close) each time a user picks up the tab. So, there's one or two settings under about:config limiting the recently visited pages cache to the latest visited only after closing Firefox -- lowest setting available (?) is 0, but hey, that's life.

Does Mozilla offer somewhere to download older versions of Firefox for Android? I've had problems since November when I got this phone and downloaded the latest version of Firefox and every update since with no fix. I'm not able to view comments or make a comment on YouTube. Other people here have the same problem. I've disabled add-ons, uninstalled and reinstalled Firefox. There's also an annoying Firefox pop-up when viewing videos in full screen that can be fixed by adjusting a setting in about:config but I've just discovered about: config has been removed!!! 90% of my internet usage is YouTube using Firefox for Android, so the problems are significant to me. An older version works perfectly on my older phone and would like that version on my new phone. Is there a way I can do this? Thank you.

I need to adjust settings in about:config but it just loads a blank page. I have tried clearing storage and cache and even reinstalling but it won't work. How can I get access to this?
