Google’s Chrome is my favorite Web browser on any platform. On Macs, though, I’ve noticed that it has a tendency to get really, really slow over time. I checked into this and I’ve found two common reasons for this and their solutions.
1) Adobe Flash crashes and slow performance
The first problem actually springs from one of Chrome’s features. Chrome comes with Adobe Flash built into the browser so you don’t need to download it. But, say you use another browser, such as Safari or Firefox, on the same Mac, guess what happens? That’s right, you end up with a downloaded copy of Flash and Chrome’s native Flash player.
The immediate result is Chrome will run slower. You will also start to see Flash crashes in the browser as the browser grows increasing confused about which version of Flash to call.
