I never understood why people think it's a good idea to enter (or even worse, store) credit card info in a phone. That's the height of stupidity, in my opinion.
It's no less secure than your PC. Actually, the average Joe's automatically-updated iPhone is probably more likely to be free of malware than his Windows PC.
It is also a lot easier to steal Joe's iPhone than it is to break into his apartment and run away with his desktop PC
Hijacking airplanes was much easier back then, because it was much easier to smuggle guns and explosives on board. Often there were little, if any, security checks, making it relatively easy to smuggle guns on board. In turn, guns make crowd control a lot easier. Today, it is extremely difficult to smuggle anything but very primitive weapons on board. And even that requires careful planning and preparation. These primitive weapons makes it comparatively easy for passengers to rush the would-be hijackers. My point is that the security checks actually do increase security. (Some of them are quite obnoxious, and seem to be dictated by airport shops rather than security concerns, though).
One interesting question is if airplane hijacking will get a renaissance when/if 3D printing becomes able to print robust automatic weapons in plastic.
However, the situation has not returned to the pre-1968 level and the number of successful hijackings continues to be high - an average of 18 per annum during the 10-year period between 1988 and 1997, as against the pre-1968 average of five.
Between 1948 and 1957, there were 15 hijackings worldwide, an average of a little more than one per year. Between 1958 and 1967, this climbed to 48, or about five per year. The number dropped to 38 in 1968, but grew to 82 in 1969, the largest number in a single year in the history of civil aviation; in January 1969 alone, eight airliners were hijacked to Cuba. Between 1968 and 1977, the annual average jumped to 41.
Now, how many aircrafts have you heard being hijacked over the last decade? Do you think that the heightened security level has nothing to do with that?
Today I was trying to lose Chrome, and go for another browser. I wasted about an hour and a half trying to sync Firefox between Android and my Mint Linux desktop, then gave up.
Then stop wasting your time. Use the XMarks addon. It is able to sync bookmarks among a number of browsers, including Firefox, Chrome, Safari and Internet Explorer. It is also available on Android.
