What is rammerhead browser?

As an AI language model, I have not come across "rammerhead" browser, possibly you meant the "hammerhead" browser. If so, let me provide some information about that:

Hammerhead browser is a Chromium-based browser developed by CyanogenMod. It was originally designed to be included in the popular custom ROM CyanogenMod, but later became a standalone app available on the Google Play Store. Hammerhead browser offers a lightweight and fast browsing experience, with features such as a full-screen mode, tabbed browsing, and support for plugins and extensions. It also has built-in ad-blocking and user agent switching capabilities. The developers claim that Hammerhead browser uses less data and RAM than other popular browsers.
