This extension allows you to comment on any page.
Not all websites support comments and even websites that do support comments will selectively disable comments on specific stories. Beyond that, websites moderate comments. Comment moderation may be for legitimate reasons, like eliminating spam, but it may be for less legitimate reasons like suppressing information that contradicts the narrative of the author or media company.
ICanComment allows readers to comment on any page without being concerned that their comment will be deleted and readers can even comment on sites and pages that don't have comments.
