Thunderbird edit email subject
I'm trying to get the add-on Edit Email Subject (EES) Works with Thunderbird 91.0 - * Downloaded from: https://addons.thunderbird.net/en-US/thunderbird/search/?q=edit+email+subject&appver=&platform=
It downloads as this file: edit_email_subject_ees-5.1-tb.xpi
Windows 10 asks what app to use to open. Nothing works. Can't open file, won't load onto Thunderbird. Running Windows 10 Home V. 20H2 and Thunderbird 91.2.0
