is there anything like this web browser in the debian/ubuntu repositories?

It's been a while since my web-browsing has really suited me. What I would really like is: A javascript-enabled web browser with a tab-based browsing system that can be controlled simultaneously using a console and a GUI. For example, I'd like to be able to... 1) open a bunch of tabs 2) go to the console and tell it something like 'copy the url open in each tab and write it, along with the html, to a file, for each open tab' in other words, I want to be able to browse with tabs at my leisure, and then write scripts that iterate over each tab. Does anything like that exist?
