Opera Portable, opens up the web to the world!
"Surprisingly, Opera [version 22] performed the best in the Octane 2.0 test, which measures how your browser will preform under the stress of games or highly interactive webpages." —Brandon Widder, (November 25, 2014)
"Off-Road mode [previously called Turbo Mode] speeds up slow connections and reduces bandwidth." —Michael Muchmore, (date)
"One step away from MALWARE" —tuliphead (a user), (March 20, 2015)

Auto update feature

  • Please read the help on how to use Opera auto update feature.
  • If auto update doesn't work:
    1. Close Opera and try copy installation_status.json and installer_prefs.json from App\DefaultData to Data folder.
    2. If still doesn't work, close Opera, backup the Data folder then delete it.
    3. Run and update Opera.
    4. Close Opera, and copy back (overwrite) Data\profile folder from the backup into the updated Opera's Data folder.

Maintenance release

  • We won't release Opera each time they're updated.

  • Flash player and/or other NPAPI plugins (Java, Silverlight) writes to Windows registry and data folders while running.
