Gmail is now overriding browser right-click to provide a custom contextual menu
https://news.ycombinator.com/item?id=6558018This is a clear example of a design anti-pattern that often crops up with new Google interfaces.
There is no setting to turn it off, and it nukes the browser's standard right click contextual menu for opening links in new tabs and windows, copying urls, etc when clicking on messages.
Designers, please just stop with this kind of thing. It's not acceptable to change the behavior of a standard. fundamental browser interface in your site design.
