Of course, the developer also notes that not every app that injects JavaScript code into an in-app browser does so for malicious purposes, since JavaScript is the basis of many web features.

To help users avoid running proprietary JavaScript, the Free Software Foundation developed LibreJS, a plugin for the Firefox web browser that blocks most, but not all, JavaScript from running.

In our tests of Chrome, Edge, Firefox, IE and Opera, the worst web browser for Windows 10 was easy to spot: Internet Explorer 11. But the best choice? That depends.

The Edge web browser gets a new logo that doesn't remind us of Internet Explorer at all, and that's likely on purpose as Microsoft shifts toward Chromium-based technology.

Microsoft open sources ChakraCore, Windows 10's Edge web browser JavaScript engine. More amazing still, Microsoft will port it to Ubuntu Linux.
