Microsoft will be rollout out Edge extension support in Windows 10 with the upcoming anniversary update which is scheduled this Summer. However, if you have been brave enough, consumers on the Windows Insider Program can download a select number of Microsoft Edge extension from the Windows Store.
Extensions is one of the top requested feature for Microsoft Edge, specially with Chrome having a entire ecosystem of extensions and add-ons in place, Microsoft needs to hurry up here, and its good to see Microsoft has started pushing them out. Microsoft did release the Page Analyser extension for Edge few days ago, and next up is from Pinterest. Installation is very straight forward, and installs directly from the Windows Store instead of a separate download and side loading process. If you get an error while installing the extension, suggest you to close the Edge browser, and it should work. That is how it worked for me.
I am sure you are aware of Pinterest, but if you really new, this service allows you to pin interesting from the web in one place which you an use to read it later, or just share it with your friends. Right from recipes from your favourite food blogs to articles you track often. Instead of plain links, they are saved as visual bookmarks, which makes it much easy to recognise, and organise things.
Once installed on your browser, all you will need is to click the extension which is next to your address bar, and it will save the existing page for you. It can do lot more than that, and you should give it a try!
