Compatibility Issues: The app is trying to run native code that isn't supported by your current hardware or browser version.
NaClWebPlugin is a browser plugin that allows web developers to embed native code within web pages. It uses the Native Client (NaCl) technology, which provides a sandboxed environment for executing native code within a web browser. The plugin enables web applications to access native resources, such as hardware and system libraries, while maintaining a secure and isolated environment. The story of the NaCl Web Plugin is

"Native Client is a sandbox for running untrusted x86 native code. It aims to give browser-based applications the computational performance of native applications without compromising safety. Native Client uses static binary analysis to detect security defects in untrusted x86 code, and dynamic fault isolation to limit the effects of bugs in untrusted code. We describe the design and implementation of Native Client, and evaluate its performance on compute-intensive benchmarks. We find that Native Client imposes a low performance penalty—typically less than 5%—while providing strong security guarantees."
