Browser Extensions Wonít Be Available in Windows 10 RTM
Microsoft confirmed at BUILD 2015 that the new Edge browser, which will be part of Windows 10, would also receive support for extensions, but thereís one little thing that everyone should have in mind when planning to give up on Chrome or Firefox and move to this new browser.
Microsoft Edge wonít come with extension support from the very beginning, as Microsoft is still working on this feature, as the company also confirmed at BUILD, so if you want to try out extensions in the new browser, you need to wait a little bit longer until they become available.
Redmond hasnít provided any specific deadline for this new feature, but it said that development would take a little bit longer because it also wants to give developers the power to bring their own extensions to Microsoft Edge with only small tweaks.
In Windows 10, any extension designed for Google Chrome should also work on Edge with just a few code optimizations, and this is one of the reasons Microsoft needs more time to bring extension support in the new browser.
