Stop Using Safari Immediately (at Least for Now) - Lifehacker

A critical Safari issue can leave some of your Google Account data and browsing history open for theft through an IndexedDB implementation bug.

Using FingerprintJS’ test site Safari Leaks, you can see this issue in action.

When you open it in Safari, the site might be able to grab your Google User ID right away.

Even if it can’t, you can open any of its test websites in a new tab, and return to Safari Leaks to see that browsing history reported almost immediately.

If Safari were working properly, this type of information wouldn’t be accessible to Safari Leaks, since the site would only be able to access data from databases created by its domain.

While Chrome on iOS might seem like the mobile version of the desktop browser, it’s really Safari with a Google skin on top.
