Browser extensions with 8 million users collect extended AI conversations

Several browser extensions with over 8 million users are found to be collecting and selling complete AI conversations for marketing purposes. Despite being endorsed by Google and Microsoft, these extensions inject scripts into webpages to intercept and capture interactions between users and AI chat platforms. The extensions claim to prioritize user privacy, but the underlying code reveals a different reality where data is sent to the extension makers' servers. This discovery raises concerns about user privacy and data security when using popular browser extensions.
