In the file:
WebExtension/data/options/index.js
the maximum for "Number of undo items displayed in the popup" is determined with:
maxResults: Math.min(chrome.sessions.MAX_SESSION_RESULTS, Math.max(2, maxResults)),
and that is 25 as I can read in the Mozilla doc about MAX_SESSION_RESULTS
But this maximum should in fact be related to the config (in about:config) for:
browser.sessionstore.max_tabs_undo
which the user can set arbitrarily.
