>Many apps (especially unofficial or wrapper-based ones like 4chan browsers) spoof the user agent string to mimic a desktop browser. This is done to:
>Bypass mobile restrictions on media or content.
>Force desktop behavior, like enabling WebM/HTML5 video playback.
>Avoid limited mobile site layouts or browser checks.
>In this case, by mimicking Internet Explorer 11, the app tricks 4chan’s servers into serving desktop WebM video content, which may not be available to certain mobile user agents.
> The app uses the IE11 user agent string to trick websites into serving desktop video formats like WebM. Your device is not running IE11 or Mozilla — it just reports that string to the server to gain full content access.
