Mozilla has released Firefox 23, an update of its web browser for Windows, Mac, Linux, and Android. The desktop apps have gained several important features, most notably a Share button, which ties into Mozilla’s new Social API. The button lets people share virtually any content on the web without having to use buttons built into a website.
Another addition is a mixed content blocker, which prevents unsecured HTTP content from being read or modified on a page that also includes HTTPS data. A Network Monitor function, meanwhile, lets developers track how long it takes for different parts of a website to load, giving them a chance to optimize a site.
