I need a certain URL to be always opened in a browser that's not systems default browser. Problem is, that this should happen even if the URL is called automatically from within a hardcoded 3rd party app.
Answer Force URL link to open with a specific browser on one hand is focussing on .webloc and .url files or is using "Open with …" menu item. On the other hand it is mentioning Choosy App; same does this answer: Open specific links in specific browsers.
How can this be accomplished with on-board resources like a script?
