Since the update to Thunderbird 60 it stopped working completly even if one deactivated extensions.strictCompatibility. Is there any way to reach the subscriptions after the update has occurred?
By default your data are located in a folder named bamboodata in the cache directory of Thundirbird.
You can use Bamboo with Palemoon to continue with the reader or to export your feed list.
To create your own collections, you must have a Mozilla Add-ons account.
