The “abyss” program is a web server not a browser. You are setting up a website on your PC essentially when running abyss. You should be running abyss pointed at the downloaded and mounted iso file. Then you access the data by navigating to localhost (or your IP if you know it) with a browser. I dont believe every option in the main menu is available. I believe only the USA options were scraped from TIS, but I could be wrong on that.
