Install the latest version of chromium.

git clone https://github.com/scheib/chromium-latest-linux.git
cd chromium-latest-linux
./update-and-run.sh

# next time

While cool, Vivaldi is also a proprietary browser.

The proxy setting is not found in the latest version. To use it,

$ vivaldi --proxy-server="127.0.0.1:8118"

To uninstall it, open the package manager to remove it.
