Beware of Browser Extensions Using MellowTel-js for Monetization

In recent developments, a researcher has raised alarms about a concerning trend involving browser extensions that utilize a monetization library known as MellowTel-js. A total of 245 add-ons for popular browsers like Chrome, Edge, and Firefox have been identified as incorporating this library. The primary function of MellowTel-js is to create a network of users who share their unused internet bandwidth, allowing companies and AI laboratories to scrape data from various websites. In return, the developers of these extensions receive a portion of the generated revenue. What makes this situation even more alarming is the way these extensions operate. According to the researcher, they inject hidden iframes and remove security headers from requests, which poses significant risks to users' privacy and security. Such practices can expose users to unwanted data tracking and potential breaches. For those concerned about their online safety, it’s crucial to be aware of these extensions and to review the add-ons currently installed on your browser. The full list of the identified extensions can be found on TabNews, making it easier for users to check if they are unwittingly using any of these potentially harmful tools. Staying informed about the tools we use online is vital in protecting our data and ensuring a safe browsing experience. If you are using any browser extensions, take a moment to assess their purpose and the permissions they require.
