Opera Detect

About

Opera Mini is a web browser that offers users an Extreme Data Savings Mode. In this mode, a lot of typically used development features are not supported (for example, transforms. See the full list).

There hasn't been a way to detect if a user is on this Extreme Savings Mode, until now. Opera Detect is a tiny script that allows you to access information about the Opera Browser a user is on, including which savings mode they are using.
