I hope this has already been suggested in the 120-something posts so far, but if not, here's my simplistic suggestion. Go ahead and use Chrome (or Chromium if you want) for your gMail tabs. But only use that browser for Google mail and apps. Do all of your other browsing/searching/whatever with Firefox or Safari or Opera or IE. And maybe switch your default search engine for that browser to Bing or one of those Bing/Google comparison engines or something. And have it either not keep cookies or auto-clear them on exit. Is it 100% foolproof? Absolutely not. But it's a reasonable step away from having them able to figure out every single thing you do.
