Other major reasons for your Facebook not responding can be because of invalid browsing data in your cache or temporary Internet cache. When you browse on Facebook, a cache file is created on your computer to store up all your recent information that you may have seen while browsing the web. Therefore, if you visit a new site and your browser doesn't have enough space in the cache to save the information, the browser tries to create a new one. This often results in the information in the cache becoming outdated and making your browser unable to read them. In such cases, simply delete the old cache files and reload your web browser.
