BiDi Mail UI
New Email To All:reply, ready for new subject/body
Do you often send emails to the same list of people? Do you press reply and then clear off subject/email body?
No longer. Open a new compose window with all recipients/cc/bcc in a clean state. You can start with a new subject line and email body.
BrowseInTab
BrowseInTab lets you open and browse any link in a Thunderbird content tab. Links are followed within the tab and back/forward navigation is supported. Also with enhanced Zoom customization and a url bar.

Unmangle Microsoft ATP Safelinks
Users of outlook.com and o365 who have Advanced Thread Protection enabled will have all URL's in emails changed to redirect them to an Microsoft filter before opening. This is a bad idea.
This plugin will change the URL back to the original value.
