Lately, when using an external interwiki prefix, instead of getting forwarded immediately, I am being asked to confirm if I indeed want to leave the wiki farm. As a regular user of such prefixes, this behaviour becomes pretty annoying over time. Though I understand this probably has been implemented for security reasons, it would be very nice to have a user preference where one can disable this request for confirmation.
Example: "luxo:Foo bar" on meta.wikimedia.org leads to Special:GoToInterwiki/luxo:Foo_bar instead of directly to https://tools.wmflabs.org/guc/?user=Foo_bar.
