ProtonMail Tab

This add-on opens a Protonmail tab at startup if none is already open.
This is ideal for accessing your Protonmail account via Thunderbird.
It is a very simple add-on that really only serves this purpose.
Nothing more, nothing less :)

Clicks on Links will automatically open in the standard Browser.

Some add-ons ask for permission to perform certain functions (example: a tab management add-on will ask permission to access your browser’s tab system).

Since you’re in control of your Thunderbird, the choice to grant or deny these requests is yours. Accepting permissions does not inherently compromise your browser’s performance or security, but in some rare cases risk may be involved.
