According to a statement from a member of the Google Chrome team, there are currently “no plans” to bring extensions to the mobile version of the browser. It’s a feature that has long been wanted, but the Chrome for Android Technical Program Manager says that they haven’t been able to implement them and still provide a good UX.
As per the AMA from yesterday:
There are no plans to add extensions support on mobile. We haven’t been able to implement these on mobile and still have it be a good user experience.
This seems a bit like the team is dodging the question here, and they don’t provide any details as to what exactly it is about the mobile experience that gets worse with extensions in the picture. One of the most popular extensions, AdBlock, would put an end to mobile ads—many of which Google themselves serves. Maybe this is what’s keeping extensions from allowing a “good user experience.”
