Ever wonder what Tab isolation is really all about and and how it can help protect you from browser crashes?
Tab isolation is a way to improve a browser’s reliability by containing the impact of a crash. Depending on how it’s implemented, tab isolation can also help contain some security attacks. There are two different implementations available today, each with different benefits.
In a tabbed browser without isolation, a problem in one tab can crash the entire browser. For example, a crash in a webpage in Firefox 3.6 or IE7 will bring down the entire browser. While modern browsers have features to recover tabs after a crash, the point of isolation is to contain the problem and prevent the browser from stopping.
