Google Chrome as an internet browser, it is the most useful and fast internet browser for ubuntu, in my opinion. You can customize google chrome with system title bars and borders.

Right click at the tabs page in a space and click use system bars and borders. So it is more embedded with your system.

Install Adblock for cleaner browsing.

Theme your browser with your theme. Get it from omgubuntu page.

You can pin and unpin tabs after 6th version.

You can use incognito windows for secure browsing.
