As the other guy said, its basically firefox but with really strong defaults out of the box. Its a good easy solution for the majority of people who want a browser that gets the job done.

I install it, get a dark mode extension, maybe change the search engine if I dont like it (Default was DuckDuckGo, but I believe that changed) and im ready to start browsing. Deleting all cookies and history every time I close it is also very nice. (Though you can make exceptions if you like)
