Permissions requested by apps and extensions

Apps and extensions that you install may have access to your data. You might also see a warning dialogue when an already installed extension or app is updated, if the item requests new or different permissions. A warning doesn’t mean that the item does do something dangerous, just that it could.

Don't install an app or extension unless you think it's safe. Check the item's ratings and reviews to see if it's trustworthy.
