With the experimental release of Firefox 51, users are soon to welcome the additional feature of displaying RAM usage by the Firefox browser on their computers. This will be an important and useful feature helping users grasp Firefox's resource utilization on their computers.

Firefox 51 browser will feature a new multi-process architecture with a single content processor separated from the browser core. Alongside new additions like sandbox, integrated sandboxing in the browser aids in protecting users against web security risks.

One of the most significant differences between Firefox and Chrome's multi-process architecture is that Firefox will never use more than one process like Chrome for each system or website. This is why Mozilla decided to release the feature to track, manage, and display RAM usage on Firefox 51 recently. Initial testing shows Firefox using over 20% of RAM even without the multi-process feature enabled.

Each process is listed with an ID for users to easily track and close applications in the Task Manager of their computers. This feature is also compared to Chrome's Task Manager, which displays running processes and allows users to easily terminate them.

However, one limitation of Firefox's displayed RAM usage list is the lack of indication of which page is being opened in any specific process. Nevertheless, with the ability to analyze processes and manage RAM, this will be a highly anticipated feature in Firefox 51.

Furthermore, one highly anticipated feature in Firefox 51 is the display of zoom level instructions, screen shrinking, which is a feature almost sorely lacking in mainstream web browsers.

Firefox is one of the leading, popular web browsers today, also one of the best in terms of speed and task handling capabilities alongside Chrome, Coc Coc, and Opera.

It's undeniable that few browsers offer offline browsing capabilities as seamlessly as Firefox. With the integrated offline browsing feature in Firefox, you can easily browse the web even without an internet connection.

The web browser developed in Vietnam, Coc Coc, has been reported by users to sometimes consume a significant amount of RAM. The reasons and solutions for this high RAM usage in Coc Coc are unclear. High RAM usage in Coc Coc leads to slow web browsing or freezing when opening multiple tabs. There are various factors contributing to Coc Coc's high RAM usage, and the best solution is to restart the browser.
