Where Opera's profile folder is located?
To see the path to Opera's profile folder, go to Menu > About Opera and check the 'Profile' line under 'Paths'.
How do I create a clean profile
Note: It will also work if you delete the profile folder in the second step.
Google (or other search engine) is leading me to the page for a different country
How can i do a standalone/portable installation
I can't select the tab when clicking on the top edge of tab bar (when Opera is maximised)
I copied Opera's profile folder to a new OS installation but my saved passwords don't show up
When doing a backup, which files should I include?
How can I disable auto-update?
I can't run Java in Opera
Support for Java has ended a while ago in Chromium based browsers. In Opera, the latest version with support for Java is 33.
Java plug-in is being discontinued by Oracle. Sites that still use it should have adapted themselves already.
What are the system requirements to run Opera?
I need to click to play Flash content even with the option 'click to play' not being selected in settings
VPN and Turbo will always use 'click to play'. To avoid it you need to add the site(s) as an exception.
