I just installed the Opera browser on my fresh installed Bluefin. I would like to change the language of the Opera browser to Dutch. For Linux, Opera asks to add the parameter: --lang=nl (for Dutch) to a file for displaying the app in another language. But how do I save or change this because all files are read-only in Bluefin?
There are some topics in the Opera forum regarding Ubuntu en Linux Mint and regular Fedora. But not for the immutable Bluefin I’m currently using.
