Why does Apple's Safari keep freezing? Last Autumn I purchased a new MacBook Pro to replace my old G4, as Safari kept freezing. Even the Apple people at Westfield Shopping Centre could not sort it out; they suggested that it was an out of date machine and not fixable! Now after 6 weeks on the new computer Safari is freezing again. The only thing I can do is press Command Q and then start all over. I don't think it has ever happened on Firefox. Any advice is welcome. Mary Baker, by email This problem has been vexing Mac users for quite a while and there are plenty of solutions doing the rounds, from a radical OS re-installation to removing updates but in many cases it is just due to Safari not getting on with the Adobe Flash multimedia content on many websites. To see if this is the cause or eliminate it from your enquiries, try a free Flash blocking plug-in called ClickToFlash. This stops Flash content from being loaded, unless you choose otherwise, and as an added bonus it may even improve your laptop's battery running times by reducing the CPU's workload.
