Many of the extensions listed in this documented are accompanied by a statement that indicates what modes and versions have the extension.  The statement has a list of document modes followed by a list of browser versions in parentheses. For any listed version the extension is in all listed modes that the version provides. Here is an example of an availability statement:

Available only in IE11 Mode and EdgeHTML Mode (All Versions).

This means that the extension is in IE11 Mode for all versions in the table above that provide that mode, and in EdgeHTML Mode for all versions that provide that mode.

If an extension does not have an availability statement, all modes of all versions shown in the table above have the extension.
