Browser Activity Monitor is a Chrome extension tailored for academic purposes, specifically designed to extract data from Rightmove property listings. It effectively collects publicly available postcode and Energy Performance Certificate (EPC) URLs by scanning the source code of property pages. This tool serves as a valuable resource for university research, focusing on energy efficiency, property market analysis, and urban studies.

Upon visiting a Rightmove listing, the extension identifies the EPC rating chart and relevant metadata, parsing it to retrieve critical information such as the property's postcode, a link to the EPC, and the page URL. Notably, Browser Activity Monitor operates entirely locally within the browser, ensuring that no personal data is collected or sent to external servers, making it a secure choice for researchers.
