  • Can anyone tell what is this?
    This is not opera.com it's "api2 dot com" so it's a malware site posing as an opera one by including opera in its name. I had a popup like this. It opened every time I opened the browser. Turned out it was coming from a video downloader extension. Source: about 3 years ago
  • Is there a way to download the official browser through a torrent or a mirror link?
    The opera.com domain is banned where I live but I still want to download the browser without a VPN (because those are also banned). Is there a torrent link or an alternative/mirror link where I can download the latest Opera One release? Thanks! Source: about 3 years ago
  • Opera Adblocker pinging opera.com?
    Apparently it "urgently needed to be removed off the network" (bullshit, you could've blocked opera.com, dumbass) I don't see why its so bad to have one kid with an unmanaged browser, like seeing "your browser is managed by your organisation" sucks enough. They disabled basically everything good about Chrome, for a time, they locked down the performance tab so we couldn't even use battery saver. Source: about 3 years ago
