10.8.2 update and now Chrome crashes, but only on my work network

Hi - I upgraded my early 2011 Macbook Pro to 10.8.2. Since then, Chrome crashes constantly. It will start and allow me to use it for a minute or two before it stops responding and I have to do a force quit on it. The strange thing is that Chrome works fine at home, but when I'm at work, I get this problem. At work, I have to connect through a fairly restrictive network, so I suspect there might be some sort of background process that might be trying to connect over a blocked port, or something like that.
Has anyone else seen a similar problem? I should mention that Safari works fine (but I need my chrome)

thanks!

Thanks for the tips. I might have to try that, especially since I've stated seeing the same problem at home, too.
