For those that were expecting to see browser extension support added in the Threshold 2 update, which is tentatively called the Windows 10 Fall Update, we have some slightly disappointing news for you. Microsoft told The Verge that extension support has been delayed until next year.
We're committed to providing customers with a personalized web experience, which is why bringing extensions to Microsoft Edge continues to be a high priority. We're actively working to develop a secure extension model to make the safest and most reliable browser for our customers, and look forward to sharing more in a future Windows 10 update in 2016.
Microsoft didn’t even qualify the delay by saying “early-2016” or even “mid-2016,” so your guess is as good as ours as to when it comes to initial public availability. It’s quite possible that the company is encountering issues implementing one of the most hyped features of Edge extensions — the ability to use ported extensions from Chrome and Firefox.
Whatever the cause for the delay, we’ll know that Edge extensions are ready for primetime when testing moves from internal builds and filters down to the millions of Windows Insiders that are testing working builds of Windows 10. And once Windows Insiders have had a chance to test things out, we should see the feature rolled out to the entire Windows 10 install base.
While the delay is a bit of a bummer, we’d prefer that Microsoft take its time release a fully functionally product than to throw us bug-riddled nonsense.
