Easy Tab Organizer von Ben

Turns a crowded Firefox window into a handful of tab groups. You always see a preview first. Nothing is regrouped, moved, or closed until you click.

What it does
- Groups loose tabs by site (eTLD+1), with readable names like GitHub
- Splits Google by product (Gmail, Docs, Drive) and Wikipedia by topic when there is enough of each
- Lets leftover tabs join a group you already made, instead of opening a second one
- Optional: cluster leftovers by title across sites
- Optional: peel idle tabs into one Archive group
- Optional: close duplicate tabs (same page, different tracking junk in the URL)
- Custom host rules: always name, never group, or merge into an existing label

What it does not do
- It does not regroup tabs you already grouped
- It does not touch pinned tabs or privileged pages (about:, file:, …)
- It does not send tabs, titles, or URLs anywhere. No account, no telemetry, no AI

Needs Firefox 139+ (tab groups API). Shortcut: Alt+Shift+O (rebindable in about:addons).
