Hello! I started using Thunderbird quite recently. After an unsuccessful installation, Thunderbird deleted it, as well as deleted the profile folder. In order to perform a clean installation of the program. But after installation, Thunderbird started, to my surprise, already with accounts, and even with add-ons installed. I have not found an answer to my question about the complete removal of the program on the Internet. The only article found from this resource turned out to be without text: just the title. Here is the link to it: https://support.mozilla.org/en-US/kb/uninstall-thunderbird. As a result, I cleaned out the entire registry, as well as all the folders found by the search. And only after that it was possible to install Thunderbird cleanly. In my experience, such deep cleaning has a detrimental effect on the Operating System. And I want to avoid this in the future. Can you tell me how to remove Thunderbird from your computer COMPLETELY? What exactly should be deleted? (This is a machine translation)
