Opera@USB is an unofficial mod of Opera, which adapts the venerable browser for installation on removable drives (USB drives). However, with Opera 11, you don’t need to use a 3rd party tool to use Opera in portable mode.
Until now, Opera Software used to offer two different setups for Windows users – one was a Classic installer, and the other was an MSI installer. With Opera 11, Opera Software has done away with both, and is instead using a custom installer. Besides being incredibly fast, the new installer also has a major benefit – it includes a portable mode.
To install Opera 11 (and beyond) in portable mode, simply follow the following steps:
- Launch the installer and click on “Options”.
- Set “Install path” as a location on the USB drive
- Change the “Install for” option to “External Device”.
That’s it! This mode forces Opera to simply extract the files to the specified destination, without touching any system settings. Also, it makes Opera read its profile from the installation folder.
