Firefox 59 brings this capability back in an initial, experimental form. It was a key element of some very popular legacy add-ons that provided the ability to manage tab groups. Tab hiding is back! Since the deprecation of the legacy extension architecture, one of the most requested features has been the ability to hide tabs with the WebExtensions API. The development team behind the WebExtensions architecture is no exception, landing a slew of new API and improvements that can now be found in Firefox 59 (just released to the Beta channel).Īs always, documentation for the API discussed here can be found on MDN Web Docs (some of the features below are just hitting the main branch as of this post, so if you don’t find the documentation on MDN, check back in a few days). Firefox Quantum continues to make news as Mozilla incorporates even more innovative technology into the platform.
