Earlier this week, Microsoft released a new Windows 10 build for Insiders that, among other things, brings support for extensions to Microsoft Edge. There aren't many extensions to play with currently, but a Microsoft engineer says the company is working on a tool to allow developers to bring their Chrome extensions to its store. "Lots of questions on this," tweeted Jacob Rossi. "Yes we're working on a porting tool to run Chrome extensions in Edge. Not yet finished and not all APIs supported."
