Readonly Attachments is a Thunderbird extension that will temporary save attached files as read-only, when viewing the attachments of an email.
Readonly Attachments is an add-on designed to work with the Mozilla Thunderbird (1.5 - 1.5.0.*) email client.
How to Install in Thunderbird:
1. Right-click the link below and choose "Save Link As..." to download and save the file to your hard disk.
2. In Mozilla Thunderbird, open Add-ons from the Tools menu.
3. Click the Install button, and locate/select the file you downloaded and click "OK".
- This version corrects a problem which caused the extension to inadvertantly override the functionality of "Save as..." as well as "Open".
