I've been having some issues with Chrome with the last few updates as well, but not quite as bad as people on here have had.
Sometimes it likes to all freeze at once, and for whatever reason, it only keeps half of my browsing history - I once was researching something important, and had forgotten to bookmark the page I found most useful. "No problem!", I thought to myself, "I'll just dig through the history until I find it!".
Well, it turned out Chrome only kept the original 3-4 pages I looked at before grouping everything together and/or completely eradicating the other 5+ pages I looked through. All it had was the original search, and 3-4 pages for the sites I looked at, and no matter how hard I tried to remember the name of the site, I didn't find it again until some more specific Googling.
Why does it only keep some of the history, and not all? I've never understood that. Firefox kept EVERYTHING.
EDIT: I just installed Firefox, and it's loading everything much faster... hmm. I may have to keep it.
