Developer extensions
We have examined 5,020 extensions filed under Developer. 18% of them have gone more than two years without an update, and 42% can read and change data on every site you visit.
Those two figures are the reason this page exists: neither is visible when you are browsing the store, and together they say more about what you are about to install than the rating does.
