Rated 4 out of 5 stars

The problem with version 53.2 has been resolved promptly with an update. I am still trying to understand the advantages of the vCard standard over the one already in Thunderbird. vCard doesn't seem to have caught on.

This review is for a previous version of the add-on (53.5). 

vCard allows you to have unlimited email addresses, physical addresses and phone numbers. It is also a bit more customizable...

There was a huge problem immediately I installed it. The Thunderbird 78.4 (64 bit) window resized - It moved to half way down the screen and enlarged so that the bottom part was now viewable. The window could NOT be resized. I disabled it, I could resize the window after that.

This review is for a previous version of the add-on (53.2). 

a corrected version (52.4) is now available at download... sorry for the inconvenience
