No browser has provided that either. In fact, browsers are by definition a security anti-feature because they are always connected to the network and the customer/user data lives on the network.
Even if they manage to solve the problem of computers getting hacked when visiting websites they are very unlikely to solve the problems of tracking and private data vacuuming.
The only difference between malware and "regular-ware" is whether the code meets certain user expectations about what it will and will not do.

How do you know? Basically every browser has a RCE vulnerability a month and has for 20 years. From ancient JPEG vulnerabilities to modern video codecs and DOM manipulation vulnerabilities.
There are a gazillion others, but this one is nice and sweet and exposes the whole web app strategy as completely bankrupt from a security perspective.
Just plain pretty TTYs.
But paid software in the 90s and 2000s was fine, no network connectivity, didn't even check for updates. Heck, a lot of freeware was fine.
Then the market changed and spyware as a service became very profitable. The genius of this Spyware 2.0 was that it offered some benefits while not abusing the collected data in any obvious ways, like stealing your money. Browsers are helpless against this, in fact they are enabling the whole business model through their support of web apps and increasingly complex APIs.
