Spoiler Protection 2.0 is a browser extension designed to help users avoid unwanted spoilers by blocking or censoring specific keywords, phrases, and websites. Compatible with Firefox, Chrome, and Brave, this tool allows users to curate a personalized blacklist tailored to their interests. By scanning text and media on web pages, it effectively conceals content that may reveal critical plot points or surprises, enhancing the browsing experience for users who want to remain spoiler-free.

Key features include the ability to hide entire sections or images based on user-defined criteria, with reported effectiveness across various platforms, including social media and YouTube. However, users have noted some limitations, particularly with YouTube thumbnails and functionality within specific applications like Discord and Steam. Despite requiring permissions to access browser data for its operation, the extension assures users that it does not collect browsing history, focusing instead on anonymized data for continuous improvement.
