Get/Send Button

  • The add-on provides a combined Get and Send button with a context menu with additional features.

    The add-on was known as "MagicSLR" until version 4.0.1 and has now been renamed to "Get/Send Button", because all functionality to send later was removed. The button still allows the manual sending of messages from the outbox, but messages are no longer sent automatically at the end of the program. The add-on now focuses on its original basic function.


    You can use the "Send Later" add-on from jikamens, which provides real send later features.

    2 Buttons and their functions

    The current version offers you several buttons which you can insert into Thunderbirds main toolbar.


    Open View ➔ Toolbars ➔ Customize... or ➔ Settings ➔ Customize Toolbars... to add buttons that are not yet in your main toolbar.

    You will find the following buttons provided by this add-on:

    2.1 In the main window (3-Pane-Window)

    • Get/Send
      This button contains all the important functions which can be accessed via the context menu (by clicking on the small arrow). What should happen when clicking on the button itself, you can configure. Go to Extras ➔ Add-ons... ➔ Extensions, select "Get/Send Button" and right-click. In the context menu, select Settings....
    • Send all
      This button corresponds to the menu entry File ➔ Send messages from Outbox . A click on it sends all messages that have been stored in the outbox. You can place the button either in the normal functions toolbar or in the title bar at the top:

      In the main toolbar:

      In the title bar:

    3 Options

    To configure the Get/Send button and set the behavior for outbox messages, go to Tools ➔ Add-ons... ➔ Extensions, select Get/Send Button and click on Settings....

    3.1 Button Functions

    • Clicking on the Get/Send button retrieves messages from all accounts or just the current account, depending on the setting. You can also set whether to retrieve accounts whose passwords have not yet been saved. The missing passwords will be asked for if necessary. If you select by default that messages should only be retrieved from Current Account, you can still later use Shift + Click to get messages from all accounts.
    • For the button Get/Send you can also set that it also sends all messages from the Outbox (and only then does the button actually call Get/Send). Sending can be suppressed as of version 3.3 if you hold down the Ctrl (or Cmd on macOS) button when clicking the button.

    3.2 Passwords

    The following option is no longer available from add-on version 8.1, since Thunderbird's own settings should not be changed by add-ons anymore (even if this was previously to the advantage of the user, since this option helped to (re-)activate the missing save option).

    4 Reset settings to default in Config Editor

    If you used the "Get/Send Button" add-on, the associated or necessary hidden settings in Thunderbird were changed by this add-on according to your selection in the options of the add-on. If you no longer have the add-on installed, or if you want to return to Thunderbird default settings for other reasons, you can do this at any time using the Config Editor (About:config).

    You have to check and reset the following settings in the Config Editor:

    Thunderbirds own/internal settings:

    • signon.rememberSignons

    Add-on specific settings:

    • extensions.getsendbutton.GetSendButton_SendYes
    • extensions.getsendbutton.GetSendButton_OnlySingleAccount
    • extensions.getsendbutton.GetSendButton_AskPasswords
