I want to substitute Firefox, Chrome, and Brave for Opera. I used to be along time Opera user. But everyday this browsers became less and less useful. Too much Plugins or none of them. I want a browser for DEVELOPERS with Javascript console, EDIT HTML in real time, read source code. Save pages for later, download pages in epub format. A BOOKMARK MANAGER capable of organizing thousands of webpages and separatin it nicely. Export pages to markdown format. Cmon guys I will stop giving you ideas!
