I finally got confirmation just before going of town for the weekend that my sine qua non extension, LastPass, works fine with the new 64-bit Chrome, so yesterday I loaded it onto both my home laptop and my work one. So far it's operating well, and "feels" more stable. None of my extensions seem to be failing that I've noticed. Next step is to see which other machines at home need updating.
Chrome Browser
Google Chrome is a browser that combines a minimal design with sophisticated technology to make the web faster, safer, and easier.
I probably should have mentioned that LastPass works fine with it seeing as I also use LP and upgraded to 64 bit a while ago.
