The author is right when he says in the conclusion that it is really difficult to do without Firefox. Although many services can be fixed with external programs, these are often only emergency solutions.
But I also learned to distinguish between the "information" web and the "entertainment" web and since I do a lot of research, programming and reading in data sources I don't need Javascript to 95%. Other points are important to me, e.g. fast loading times, low CPU and minimalist design. But you have to do without many features.
Text-based web browsers are cool, yes. But if you're not in the Linux scene and ride on (e.g. Manjaro I3) it's incredibly cumbersome and exhausting.
