Safari on Windows Vista is known to crash frequently, and there is no easy fix. However, there are a few things you can do to minimize the chances of Safari crashing. First, make sure your computer is up-to-date with the latest security patches. Second, try disabling some of Safari’s features that may be causing it to crash. Finally, try using a different browser if possible. ..
This is a good example of where Vista’s Compatibility Mode comes to the rescue… we can set Safari to run in compatibility mode for XP and eliminate the majority of the crashing problems.
To set the compatibility mode, just right-click on the Safari icon, choose Properties and then the Compatibility tab.
Check the box for “run this program in compatibility mode for:”, and set the option to “Windows XP (Service Pack 2)”. Just remember to do this for any shortcut icon that you usually use to launch Safari.
I’ve been running it for about 2 hours now, doing everything I can think of to crash it, and haven’t had a problem so far.
