Adjacent tab grouping — new tabs join the group they were born next to

Open a tab next to a group and it joins the group by itself.

How does adjacent tab grouping work?

Direct answer

Open a link from a tab that already sits inside a group, or drag a tab so it lands beside one, and Flocci Tabs adds it to that group automatically. It matches the mental model you already have: things that sit together belong together. No re-dragging, no right-click menu.

What it does

  • Works for links opened in a background tab from inside a group.
  • Works for tabs you drag into position by hand.
  • Keeps research threads intact instead of scattering follow-up tabs across the strip.
  • Toggleable from the options page if you prefer strict manual control.

Under the hood

Driven by chrome.tabs.onCreated and onMoved with a positional check against existing group boundaries in the same window.

Adjacent tab grouping — questions

Straight answers, no marketing detours.
Does adjacent tab grouping need a Flocci account?
No. This runs entirely on your device and works the moment the extension is installed. No sign-in, no account, no network call.
Can I turn adjacent tab grouping off?
Yes. Every behaviour is toggleable from the extension's options page, and rules, colours and keyword filters can be rewritten or exported as JSON for backup.
What exactly leaves my browser?
Nothing. This feature is local-only — it uses Chrome's tabs and tabGroups APIs on your machine and makes no network request at all.
