This add-on is a follow on to Keyconfig which is no longer supported.
It is aimed at power users. Please look at the GitHub site before leaving a one star review about documentation or usability.
Quote Colors & Collapse
Configure text and background colors of quotes in mail and news messages. From up addon version 3 (Thunderbird 91) you can collapse quotes.
No Message Pane Sort
No Message Pane Sort prevents accidental resorting of the message pane by disabling mouse button clicks on the column headers, thus, locking the sorting order of your emails.
It is still possible to sort messages by ctrl-clicking the header.
