Permission “Access to all data on computer”

When I’m trying to install the Chrome addon, the following message appears: Access to all data on computer. Why is that

Don’t worry, we don’t need your data! It’s just that the addon requires an additional module in order to function properly and every time such module gets installed, Google requests permission with the abovementioned message. In fact, the addon doesn’t even require any additional data. Please, note that every module is checked by the Google Chrome team manually, which guarantees its safety and reliability.
