to add and delete is no problem. but I can not change address book contents. it's not saved.

thanks for your kindness. I launched in safe mode. but it still have a problem. (addons is disabled)

installed addons are the enigmail and XNote++ and it's not out of date and no plug-ins

I tried to launch as administrator mode but it's not solved too.

I have 5 addresss book. and I found 5 *.mab files in profile directory.

all of them have same problems.

if I edit some field (e.g. edit name abc to abcd ) click ok button -> no action and edit window is not closed click cancel button -> edit window is closed, and name looks changed in list. but after closing and re-open address book. it's not changed

I created new Address book (newADDR : in attached image file) and try to add new test contact. but ok does not work. cancel button just close window.

I said new contact is added automatically when I send email to someone who is not in my address book.

I also try to copy some contact to newADDR by drag and drop. it's okay. I try to edit contact in newADDR. It happen same problem.

I also said "to add and delete is no problem." my fault. it's incorrect information

'add contact' is only possible automatically when I send email to someone who is not in my address book. 'delete contact' is possible in all address book (I tested)

rebuilding mab file is already done. but it does not solved the my problem.

I make new profile as you suggest. (show IMG file) and try to add new contact to personal address book. but it's same. not work

collecting mail is work. and I can move contact in collected address book to personal address book and try to change name. not work.

Is there any way to show TB's some log ?

I found some error log. ( using error console as you said ) when i click 'ok' button Type Error is occurred (show attached image) it's javascript error in abCard.js:571:7 abCard.js 571 line is below

doc.getElementById(kVcardFields[i][0]).value);

and 'TypeError : this.chromeUtil...' is shown when I click '더 알아보기' which means 'show more'

please show attached image first.

after launching TB, I open browser console window. first two TypeError (green line) is shown (I do nothing but launch TB)

and I open address book window and open contact window then 3rd error (red line) is shown

and then I click 'OK' button in contact window, last error is shown

abCard.js file is found in "C:\Program Files (x86)\Mozilla Thunderbird\omni.ja"

omni.ja file seems jar file and I unzip this file. then found abCard.js in omni\chrome\messenger\content\messenger\addressbook\

but I can't anymore

I posted to bugzilla including this page link

Thanks for you support.
