function getDisabledRuleIds — Returns the list of individual disabled static rules from a given static ruleset id.
function updateStaticRules — Modified individual static rules enabled/disabled state. Changes to rules belonging to a disabled ruleset will take effect when the ruleset becomes enabled.

api mailTabs

function getSelectedFolders — Lists the selected folders in the folder pane. Does not include folders which are context-clicked, but not selected. The context-clicked folders are always returned by the menus.onClicked event of the menus API.

api menus

type OnClickData.selectedFolders — The selected folders in the folder pane. Only available for the folder_pane context. The accountsRead permission is required. The returned selection includes the folders which would be affected by a context action through Thunderbird’s UI, which may not be the currently selected folders. For example, if the user has multiple folders selected and opens the context menu for a folder outside that selection, only the folder for which the context menu was opened, is returned.
type OnShowData.selectedFolders — The selected folders in the folder pane. Only available for the folder_pane context. The accountsRead permission is required. The returned selection includes the folders which would be affected by a context action through Thunderbird’s UI, which may not be the currently selected folders. For example, if the user has multiple folders selected and opens the context menu for a folder outside that selection, only the folder for which the context menu was opened, is returned.

api messages

function listInlineTextParts — Lists all inline text parts of a message. These parts are not returned by messages.listAttachments and usually make up the readable content of the message, mostly with content type text/plain or text/html. If a message only includes a part with content type text/html, the method messengerUtilities.convertToPlainText can be used to retreive a plain text version. If the message is encrypted, the inline text parts of the decrypted message are listed.
type InlineTextPart — An inline part with content type text/*. These parts are not returned by messages.listAttachments and usually make up the readable content of the message, mostly with content type text/plain or text/html
type MessageAttachment.contentId — The content-id of this part. Available for related parts, which are referenced from other places inside the same message (e.g. inline images).

api scripting

type RegisteredContentScript.matchOriginAsFallback — If matchOriginAsFallback is true, then the code is also injected in about:, data:, blob: when their origin matches the pattern in ‘matches’, even if the actual document origin is opaque (due to the use of CSP sandbox or iframe sandbox). Match patterns in ‘matches’ must specify a wildcard path glob. By default it is false.
type RegisteredContentScript.world — The JavaScript world for a script to execute within. Defaults to “ISOLATED”.
