I have been searching for things like "chrome tab auto recover crash" and "chrome tab auto reload" but I can't find any other experiences either way that explain what's going on. So all I can tell you is that I suspect it's an extension you might have installed that periodically checks/reloads tabs, if it isn't crashing. Because I haven't seen tabs appearing to refresh itself and I use chrome for about 3 hours every day.

Interesting. I use Chrome for far longer each day, and usually never even close it except, obviously, when rebooting (which doesn't happen often).

As far as I know, none of my extensions should be reloading the tabs. Here are my extensions:

Adblock Plus for Google Chrome™ (Beta) - Version: 1.1.4

Facebook Disconnect - Version: 1.0.2
Stop Facebook from tracking the webpages you go to.

How did you make that list? Did you edit it by hand? Or could you copy it directly using some nice extension? And how did the titles get bold? Is it possible to paste formatted text into comments here in the forum?

Do you want to make it install by default?  Fine, but still give me the choice.  Just like the developer has the choice to NOT support older versions (or to charge for that support), I should have the choice NOT to install the newer version.  Taking away that choice is NEVER a good idea.

I agree.

It seems like to avoid an automatic upgrade you will have to block the address it uses to check for (or download) upgrades in your firewall or local proxy. I use Privoxy and could block it there (although I personally don't need to).

There is always a practical solution. :-)

YES! It is a MIRACLE! The ding is gone!

Thank you! You rock, mouser! :Thmbsup:

And thanks to Bamse and others who contributed to finding the cause!
