I keep getting "modification_failed" errors when I try to modify or add an event into my Google calendar. I deselect "read only", but the error returns. Then Thunderbird freezes and I have kill it in the Task Manager. When I restart Thunderbird my calendar is set as "read only" again.

How did you add the Google calendar to TB 78? TbSync 2.16 is the only add-on that currently works.

Are you running 78 on a profile that was run with 68, or is it a new profile that was created with 78?
