Microsoft today announced a slew of incoming Edge extensions. Partners announced include Pinterest, AdBlock, Adblock Plus, LastPass, Amazon Assistant, Evernote, and Page Analyzer powered by Vorlon.js.

Exactly two weeks ago, Microsoft released a new Windows 10 preview build with Edge extension support, arguably the most important feature missing from Microsoft’s new browser. But the company only released three extensions: Mouse Gestures, Microsoft Translator, and Reddit Enhancement Suite.

Support for extensions was supposed to arrive by the end of 2015, but the feature was delayed until this year. Microsoft still hasn’t shared how long it plans to let testers play with it before releasing the functionality to all Windows 10 users.

Unlike Internet Explorer’s native add-ons, Edge’s extension platform is powered by web technologies. Microsoft has also made it easy for developers to port their Chrome extensions over to Edge.

Once the feature debuts, all extensions will be vetted, delivered, and managed through the Windows Store. Until then, extensions need to be sideloaded manually.

On the whole, today’s announcement at Build 2016 is rather disappointing. Having a total of just 10 Edge extensions is a joke. Microsoft needs to ramp this up, and quickly, or Edge extensions won’t be much more exciting than IE add-ons.
