| Mozilla improves Firefox's protection against malicious code |
Mozilla has introduced a new security feature that will make Firefox the most secure browser for customers. Mozilla announced that version 95 of the browser has introduced a security feature designed to limit the damage that bugs and security breaches can cause to browser code.
The feature, called RLBox, was developed with the help of researchers from the University of California, San Diego, and the University of Texas. It was originally released as a prototype last year. It is now available for the Firefox desktop and mobile browser.
The heart of RLBox is Sandbox technology. This means that it can isolate the code so that the vulnerabilities do not harm the entire system.
Sandboxing is a widely used security method in the industry. All modern browsers use sandbox to protect users from malicious code. Web content protection is put in place to prevent malicious websites from invading your browser.
However, the problem is that many advanced security vulnerabilities use a number of vulnerabilities to bypass this protection.
RLBox is different from this traditional method, but it does not require the same performance and memory as the traditional method.
This helps protect important browser subcomponents so that the browser can treat them as untrusted code while they are running in the same process.
With RLBox, Firefox converts the process to WebAssembly and then converts it to native code.

This approach has two important advantages because it prevents code from moving between different parts of the program. Restricts access to certain areas of system memory.
RLBox is used to isolate the five components of Firefox including Graphite, Ogg, Hunspell, Expat, and Woff2.
If the system works as expected, the company finds that even undiscovered vulnerabilities in one of the five components pose no threat to the browser.
According to Mozilla, this means that if a bug or vulnerability is found in any of these subcomponents, the Firefox team will not have to prevent them from opening the browser completely.
Mozilla acknowledges that this is not a comprehensive solution and that this method is not applicable anywhere, such as for performance-sensitive browser components. But she said she would like to see other browsers and software projects implement the technology. He also said that he intends to use it with more browser components in the future.
