A team member shared a Google Form for me to fill out. Strangely that form URL could not open in Firefox. It would not load with this error:
The page isn’t redirecting properly
An error occurred during a connection to docs.google.com.
This problem can sometimes be caused by disabling or refusing to accept cookies.
I did not have any setting in Firefox to disable or refuse some cookies. So that error was wrong. But it gave a hint that the problem might be caused by cookies.
I went into the Firefox options and deleted all cookies involved with the URL google.com. There is no need to delete all cookies, just those that have this URL. Once I did that, the Google Form URL opened correctly.
You try to open one of the websites of Google, say Gmail, it does not open in Chrome. Instead you see in the address bar that Chrome is flailing about, switching between accounts.google.com and mail.google.com. Or sometimes Chrome just gives up and says that it got stuck in an infinite redirect loop.
This problem happened to me when I blocked cookies on some Google websites, say accounts.google.com and allowed it on other Google websites, say mail.google.com.
To fix this problem, you may have to allow all Google websites to set cookies. Or at the very least you will need to tweak these settings until Google websites do show up.
You can do all of this in Chrome at Settings > Privacy > Content Settings > Cookies > Manage exceptions.
Tried with: Chrome 27.0.1453.93 and Ubuntu 12.04 LTS
