@sgunhouse Well something went wrong. There were also 2 json files in the snap opera folder
1 had binary code at the top, couldn't read it, but it also, I could not unset Sougou as the default search engine.
a .js file is text, as far as I know, but the browser.js I had was binary code, not human readable.
You may like to mention this to those responsible for Opera.
I purged Opera, and installed Vivaldi. No problems with Vivaldi!
