About Game Over

Made this on a whim to keep students trying to play .html games in a school environment on track 10/15/24 *Added popup window when clicking the extension, as well as updating the redirected site* 10/22/24 *Fixed it so it also redirects websites as well as local files* 11/6/24 *Revamped the whole thing, gave it a much simpler approach as well as added an admin menu and a hardcoded whitelist with the ability to manually add urls to temporarily unblock a site* 4/30/25 *Added wss blocking for eaglercraft's relay servers *Added fingerprinting for time wasting code pasted into compilers * 5/1/25 *Added toggle checkboxes to disable .html/.mhtml, fingerprintint and wss blocking features* *Updated blocking messages* *Updated whitelists* 5/2/25 *More whitelist adjustments and some back end work so whitelist syncs up before blocking rules take effect* 5/5/25 *Hopefully fixed local .html files from being loaded* *Whitelist hopefully loads again now* 5/8/25 *added paste interceptor to replace proxy/game copy pasta with an ascii image* 5/19/25 *Upgraded from local .html to fingerprinting proxy/game code and has a working copy/paste replacer if it finds certain keywords. Added checkboxes in the admin panel to enable/disable certain functions* 5/29/25 *Added admin logging panel to help debug, and whitelist false positives. Also fixed colors in light mode for the weirdos who aren't using darkmode* 10/20/25 *Added rom detection* *Removed google ai overview from searches* 11/6/25 *Added css overlay to hide google games* *1/22/26* Added some new features: Tab-Cloak & Protocol Interceptor: Blocks attempts to bypass security using about:blank, blob:, or data: URLs in new tabs. Brand Impersonation Shield: Automatically blocks sites that attempt to "cloak" themselves by using titles from trusted platforms (e.g., Google Drive, Canvas, Schoology, Quizlet) on unauthorized domains. Enhanced Proxy & VPN UI Scanning: Uses a specialized selector list to detect and block functional proxy elements like VPN panels, unblock buttons, and specific "Ultraviolet" (uv) address bars. ***
