Setting up Opera Portable

Opera is my favorite browser on Linux, so it makes sense that when I have to use a Windows computer I would use Opera Portable running on a USB stick.

Install Opera Portable as you would any Portable App.

Opera Portable’s main files, what would be analogous to ~/.opera on a normal installation on Linux, are found in %drive%\PortableApps\OperaPortable\Data\profile\.

The following assumes you have already configured Opera generally and (optionally) as a mail and Usenet client.

Most configuration is done is the Preferences window (Settings – Preferences). Portable-specific preferences I set include:

  • General – Startup: Continue from last time.
  • Advanced – Notifications: Disable notifications for new messages.
  • Advanced – History: Remember 1000 addresses (the minimum). Memory cache automatic. Disk cache 100 MB; empty on exit.
  • Advanced – Security: Set master password. Ask for password once per session. Use master password to protect saved passwords.

Optionally, set portable-specific mail client preferences. Open each mail account and set:

  • Incoming: Enable low-bandwidth mode. Do not make messages available offline.

Optionally, set portable-specific Usenet client preferences. Open each Usenet account and set:

  • Incoming: Do not make messages available offline. Do not check for new messages every X minutes, but do include this account when checking manually.

TODO: Finish this section. In particular, document how to keep Opera’s usage of the USB stick’s space to a reasonable minimum when using the email or Usenet client or feed reader.

A common problem is that Opera Portable fails to start, displaying the error “Another instance of Opera, Portable Edition is starting. Please wait for it to start before launching it again.” If you are sure that no other instance is running, delete the “I am running” lock file at %drive%\PortableApps\OperaPortable\Data\PortableApps.comLauncherRuntimeData-OperaPortable.ini.

The Portable Apps project does not have a support forum dedicated specifically to Opera Portable, but searching the Other Apps Support forum reveals numerous relevant threads.

Support options for the Opera browser generally can be found in the Opera browser article.

I haven’t tried it, but another portable version of Opera is Opera@USB.

These notes are based on Opera Portable 11.50 and were last updated 20 December 2011.
