I am having some trouble viewing certain webpages, including Google Sheets (the other that I noticed was a more graphics-heavy website called "Wheel Decide" that lets you spin a virtual wheel to, well, decide on things. That one wasn't too surprising, but there aren't very many graphics on a spreadsheet). I don't have any problem with Google Docs, or Pages, but when I try to open or create a spreadsheet, I'm getting an unviewable page. It looks a little like a cloned, upside down, mirrored image of other tabs I'm running all scrambled together. I believe my browser is up to date (It installed update 44.0.2 on March 1st). I just changed to Firefox because Chrome does not support my operating system anymore. I'm running Mac 10.6.8. It's an older 13" white MacBook that has been starting to have some difficulties loading graphics (white lines flash across the screen, but go away after a second or less), but it can still load Google Sheets and the other websites that Firefox won't load when I use Chrome. Any advise you can give me would be great. Thanks
