After trying different browsers on android I found Privacy Browser to be what I need. It have encrypted backups,Domain settings,jsless by default,Deleting all site data and Most usable UI. Only issue is It is based on webview and I am using system default webview as my device is nonrooted so how secure is to go this way?
From https://divestos.org/pages/browsers : While WebView browsers utilize the Chromium WebView, they cannot offer any per-site process isolation. Using any WebView-based browser is largely not recommended as they are inherently limited due to the WebView merely being a widget for adding web content to an app and are not intended to create a full browser experience. TLDR: Don’t use WebView browsers.
I have readed it earliar but do not see any much efficient alternative. Encrypted backup,nice interface to manage domains and simple ui
To me fluff doesn’t mean much if the browser is insecure. But you do you.
