Report an Issue and Get Troubleshooting Help
I was having the same problems since the last update to chrome. Tried uninstalling and reinstalling several times. Finally looked on facebook help and they told me to clear my cache and cookies:
Google Chrome for PCs
Click the "wrench" icon in the top right-hand corner and select "Options."
In the "Under the Hood" tab, click the "Clear browsing data..." button.
Make sure that "Empty the cache" and "Delete cookies and other site data" are selected.
Click on "Clear browsing data."
Exit and relaunch the browser.
