Back in August, the release of the Windows 10 Anniversary Update finally brought browser extensions to Microsoft Edge, with a first wave of extensions being released on the Windows Store. Earlier this year though, Microsoft teased on its Windows 10 Roadmap website that Edge extensions were also in development for Windows 10 Mobile, but Microsoft has since updated the page to remove any mention about Windows 10 Mobile.
However, today a tweet from the official Windows France Twitter account mistakenly said that Edge extensions were available on Windows 10 Mobile (via Aggiornamentilumia.it). The tweet, which has since been deleted, linked to a May 2016 article from French website WindowsGeneration, reporting on the fact that Edge extensions were in development for mobile according to Microsoft’s Windows 10 Roadmap website (that’s no longer the case, like we explained in the above paragraph).
So, it pretty much seems that one of Microsoft France’s community managers didn’t do enough fact-checking here, and that's why the tweet has been quickly deleted. As of today, we have absolutely no proof that Microsoft is still working on bringing Edge extensions on Windows 10 Mobile, and the latest Redstone 2 builds doesn't tease anything about them either.
We do hope that Microsoft hasn't completely abandoned the idea though, as browser extensions may well help its mobile OS stand out against iOS and Android. However, we guess that Microsoft is probably betting on Continuum being Windows 10 Mobile's real killer feature going forward.
