# Workaround known to work:

(as described in Thunderbird’s [release notes](https://www.thunderbird.net/en-US/thunderbird/60.0/releasenotes/#known-issues)):

- go to the config editor (Settings -\> Advanced -\> General -\> Config Editor)
- search for `network.cookie.same-site.enabled`
- set it to false

For your own security you should set it back to true once this issue is resolved.\

# Unconfirmed workaround by other users:

I have found a safer workaround: If you have changed it already set network.cookie.same-site.enabled to true again. Then set all third party cookies to be denied and add an exception for the domain your Nextcloud installation is running on.

Settings \> Privacy \> Web content \> Exceptions \> Enter `https://your.domain.org` [`/nextcloud`]

I have tried both of the workarounds listed above. I am not sure this this is related (beginner/sorry) but while my calendar is showing in Thunderbird (60.2.1), it will not allow me to choose or turn it on. Please see attached.

I had the same issue testing all workarounds to finally discover that is was the TOTP security setting in my nexcloud account that was the problem. removing it was the solution.
