Chromium changed look after I had installed "security updates", and the option to change it back to a usable state is gone.
So, uninstall, reinstall old version. Added block for updating it.
Filed bug report. It was categorised as "WONTFIX", and merged with others, with a comment that I should use the "feedback form."
THIS IS NOT AN OPINION, YOU WORTHLESS PIECE OF ****! The interface has regressed to a less usable, less secure state, by objective means of measuring according to established user interface principles. I've got a college degree in this stuff.
GAH! Effing hipsters at google!
