Can Ping but can't browse

[stuartiannaylor]

Can't seem to get by this problem on Linux Xenial Mate 104 build. Have had problems on others too. Hoping some Linux experts can point me in the right direction.
1. Etcher image to SD (Samsung EVO Plus 32GB).
2. Boot in Rock64. No changes to the build.
3. Firefox - click icon.
4. Sorry - Firefox has a problem, quit or send message to Mozilla.
5. Applications - Internet - Chromium Browser
6. "Oh snap" window displays. No browsing for you.
7. Terminal - ping google.com, ping pine64.org, ping yahoo.com, ping my router, ping 8.8.8.8, ping 8.8.4.4 - all work till the cows come home.
8. Terminal - apt-get install midori.
9. Terminal - midori - can browse per usual.
10. Run the Firefox and Chromium browsers from the terminal - same error messages but lots of terminal messages. Here they are;

rock64@rock64:~$ chromium-browser

Dunno just got the rock delivered earlier today.
Typing from Chromium but firefox works fine.

Etcher -> eMMC but that should make no difference.

Code:

sudo apt-get update -y
sudo apt-get install linux-rock64 -y

should return

linux-rock64 is already the newest version (0.5.10).
