Okay let's try removing the opera snap, and installing it as a .deb
Open a terminal and run:
now run:
gksudo xed /etc/apt/sources.list.d/opera-stable.list
and when a blank file opens, make it read
# This file makes sure that Opera Browser is kept up-to-date
# as part of regular system upgrades
deb https://deb.opera.com/opera-stable/ stable non-free #Opera Browser (final releases)
SAVE the file and exit the text editor.
Back in the terminal run:
wget -qO- https://deb.opera.com/archive.key | sudo apt-key add -
then
then
sudo apt-get install opera-stable
Now see if Opera is in the main menu at
Menu > Internet > Operaand test it works.
