It fails on Safari 8.0 as well, on a different computer. (I don't
have Safari 8.0 on this one, because it has not been updated to Yosemite
It worked with LastPass and Safari 7.1 until today.
It seems that users get Zoho's updates at different times
(I'd guess depending on where you are, what server you get routed

later for others. Just wait...
