It’s now a little more than a year since Microsoft first brought extensions to Edge. After so long you would expect the selection of addons to be overwhelming — but that’s far from being the case. In all, there are only 70-odd Edge extensions available, and Microsoft has been moved to explain why.
In a blog post, the company almost apologetically explains that it is “building a thoughtfully curated ecosystem,” citing concern over quality and a fear of diminishing the user experience. What some might describe as “slow,” Microsoft refers to as a “purposefully metered approach” to new extensions, and you probably shouldn’t expect things to speed up a great deal any time soon.
Edge is just never going to even get close to winning browser market now without a much move developed extensions market. That’s not going to happen when extension companies can write for Google and get 80% or more market covered.
