Thunderbird 커뮤니티 포럼

My contacts address book is provided by Apple iCloud, of which I have added contacts with avatars for every contact I've received legitimate emails from. However, Thunderbird fails to render these avatars. The result looks like the attachment. Perhaps Apple is using HEIC for them?

After upgrading from Fedora 21 to Fedora 29, I cannot update my Thunderbird address book. I have tried disabling add-ons and deleting the abook.mab file, but I still cannot add a new entry using the pop-up GUI even to an empty address book. I can add a new entry by right-clicking an existing email address, and I can delete entries, but the "OK" button in the GUI does not work. Other users on my system do not have the same problem so something appears to be corrupted in my account. When I use the developer_toolbox then I open the address book I get these:

RangeError: invalid language tag: en-US-u-va-posix-u-ca-gregory-nu-latn mozIntl.js:78:31 RangeError: invalid language tag: en-US-u-va-posix-u-ca-gregory mozIntl.js:78:31

When I click "OK" in the GUI I get these:

TypeError: aDatepicker.yearField is undefined[Learn More] abCard.js:826:3 TypeError: birthdayElem.monthField is undefined[Learn More] abCard.js:575:7

Thanks. Any assistance would be greatly appreciated.
