"Snap" update issue

 "Ubuntu" uses "Snap" for "Firefox" by default since 22.04 which has this annoying "pop-up" warning every other day. I wrote the following script to aid upgrading of "Snap" apps.

#!/bin/bash
sudo killall firefox
sudo snap refresh
echo -e "\nIf specific Snap app is still pending update, please use the following commands.\nsudo snap refresh <appname>\nkill <pid>\nsudo snap refresh"

DoH update

 Support for DNS over HTTPS (DoH) in browsers has improved since I last researched it.

In "Brave", it is just a simple click to enable it.

 

For other browsers like "Firefox", you can refer to this link to enable DoH using "OpenDNS".

However, the "OpenDNS" option fails for some sites so I switched to "Cloudflare" instead.

DNS security on Android

 Android has come a long way. I only recently found out that I can define my own DNS settings instead of relying on my ISP's DNS servers which I don't trust to be secure enough.

Whilst my go-to DNS on "Desktops" is "OpenDNS" but it is not compatible with the "Private DNS Mode" in "Android". 

I am using the DNS offering from "Cloudflare" instead. "Google" is an option but do note that you will be surrendering even more information about your traffic to them.  

Easily access the section by searching DNS in "Android" then entering the DNS service's hostname that you want to use into the "Private DNS provider hostname" field.
