I've been using this extension for years, I've never had any security and performance issues in my Internet browser. Now, according to Opera, the extension is not secure, however in the own web of savefrom.net they show how the app as the extensions for browsers are totally safe according to a report of Norton Security (https://safeweb.norton.com /report/show?url=savefrom.net)
What is the problem of the extension? Security problems? I trust that isn't the problem of the app. I would like Opera to be transparent with its users and not disable useful extensions like this, without explanations beyond a simple sentence, where they also indicate that they "believe it is malicious" although they do not show it in any way.
Completely disappointed with Opera Browser.
