My name is Steven from San Francisco,CA.I appreciated andruis's comments further down the list of comments because he had this same issues with a newer version of Opera.Mine is Opera 25 on the Snow Leopard Operating System on my Mac.I had no problems with it for 3 1/2 years until I saw this message out of the blue on September 3,2020.I e-mailed Opera headquarters the next day and they did responded the next say and they told me Opera doesn't support Snow Leopard OS anymore,but andrius has a new version with same problems.If the level of the browser is compatible with the level of the OS it should work.
