HAR recording: startHar and stopHar record one tab's requests with headers, cookies and bodies and print a HAR 1.2 file (firefox-ctl stopHar > page.har). Off by default: tick "Allow HAR recording" in the add-on preferences first. Adds the webRequestBlocking permission for reading response bodies. Requires firefox-ctl CLI 1.0.4.

New cookie commands: exportCookies, setCookie, deleteCookies and importCookies read and write the cookies of the tab you drive, so a login can be exported, moved into the managed window or cleared from the terminal. Requires the new cookies permission.

Child frames: watchFrames, listFrames and unwatchFrames observe the cross-origin iframes of one tab on demand, and --frameId runs getContent, click, type, waitFor and the other page commands inside such a frame (hosted payment fields, consent banners in iframes). Adds the webNavigation permission for that. Requires firefox-ctl CLI 1.0.2 for the new commands.

getPageState returns a selector for every link, button and input; click and getElementInfo can target an element by its visible text (--text, --scope); getContent returns the rendered text and supports --tail; getElementInfo suggests alternatives when a selector misses. Requires firefox-ctl CLI 1.0.1 for the new flags.

Initial public release.
