User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:36.0) Gecko/20100101 Firefox/36.0 Build ID: 20150222232811 Steps to reproduce: i just replied to a thursted email with pictures. the picture where company logos. Actual results: all the company logo pictures where replaced with a picture from another email. during typing of the email i saw a large empty square where the picture suppose to be. thunderbird probably had problems with the picture. the picture also happened to be a very private confidential product image. Expected results: well this obviously shouldnt happen, the pictures should not have been replace with confidential images.

imap account?

(In reply to Wayne Mery (:wsmwk) from comment #1) > imap account? i am using a simple isp upc mail account. company used its own email server i think. i am very confident that thunderbird swapped a picture after i hit reply. at first the picture was just a white big square. so it had problems with the picture. when i got a mail back from the company, i saw in the email that all the company logo pictures had been replaced with my picture from another email.

Same phenomenon as bug 766495?

yes exactly the same. it did not show up as a simular bug when i reported this bug.

Thanks bert.
