How to allow outdated plugin (e.g. Adobe Flash Player) in Opera 30.0.1835.125 (or later)?
Solution 1:
Till there is no way to allow outdated plugins in the new versions, you could disable automatic updates and stay with version 30.0.1835.88 (or earlier).
If you already have 30.0.1835.125 (or later), you can:
- uninstall the browser (preserving user data if you prefer)
- disable automatic update
- download and install an earlier version from the official FTP server
