A few months ago I started using Google Chrome. It was quick, nippy, uncluttered and worked more smoothly than Safari with gametrailers.com's (and consequentially, MTV's) video streams. Yesterday, my Mac blacked out. Literally switched itself off spontaneously. No power cut or anything, just the Mac. I turned it back on again to discover that Chrome (which had been open on Facebook I think) would no-longer automatically log me into any websites, I have to sign in manually every time I use Chrome to visit the likes of Facebook or DesignForums. It's annoying, and I am now using Safari again. Which is fine, I guess. I've uninstalled and reinstalled and the problem persists. Any thoughts?
