All software has problems, some are just the result of adding other vulnerable software. I will stick with my Firefox.
Actually most everything that has to do with computers is broken as they can't fix themselves and are only as good as people that make them and unlike a car for example the company that builds it has control over all aspects of the car,even though they don't make all the parts.The problem now-a-days is some things are made to break.
