Devs are still working on the TabHiding API so the full functionality will be back the next year.

No, this is out of date. It points at this plugin, which no longer works: https://addons.mozilla.org/en-US/firefox/addon/tab-groups-panorama/

Any news on this, please?

TabHiding API is done and there's plenty of extensions doing Tab Groups.

For instance:

• https://addons.mozilla.org/firefox/addon/basic-panorama/
• https://addons.mozilla.org/firefox/addon/simple-tab-groups/
• https://addons.mozilla.org/firefox/addon/conex/
• https://addons.mozilla.org/firefox/addon/power-tabs/
• https://addons.mozilla.org/firefox/addon/panorama-view/

Thanks for quick reply.

I've just discovered that Simple Tab Groups now has fast group switching (don't reload all tabs), which solves it's main fault.

I'll check the others as well.

Is TabHiding API something only devs would use to develop new features, or can I use it directly as a (non-dev) user?

WebExtension APIs are interfaces that addon devs may use. It's only for addons.
