My University removed all email accounts from their server and highly recommended a vendor that serves commercial accounts. The University recommended we not use Thunderbird so I complied with the University recommendation. I am displeased with this change. I was extremely satisfied with Thunderbird that I used during my student years & employment and for 20 years following my retirement. I do not need Thunderbird at this time and deleted the app from my computer. Subsequently I discovered a charge on my Visa statement from Mozilla Thunderbird in the amount of $10.90. What is the reason for this charge that I was not expecting or authorize? Thank you for your consideration. Donna Gould, [email protected]
