The page you're looking for
is already findable.

Press ⌘⇧K (Ctrl+Shift+K on Windows and Linux) and start typing. GoToTab searches your open tabs and your browser history at once and shows both in one list, so you don't have to decide up front whether the page is still open.

Yes, on every plan and without an account. Searching your own browser history is free, along with tab search, switching, unlimited collections, tab groups, and slash commands. Pro adds the tabs you closed on your other devices.

Because including your history in search results means reading your history — there's no way around that. It is read locally on your device, at the moment you type, purely to decide what to show you. It is never transmitted to us and we keep no copy. If you'd rather not, the switch in Settings turns it off and search covers your open tabs only.

No. Local history search never sends anything anywhere. Separately, if you're on Pro, GoToTab records the tabs you close (title, URL, close time) in your account so you can reopen them from another device — that's a focused log of tabs you had open, it's optional, and you can clear it whenever you like.

Ninety days. Beyond that it's rarely what you're reaching for, and an unbounded search gets slow on a heavy profile.

No — anything already open appears once, as a tab. Offering to reopen a page you're currently looking at is just noise, so history results skip whatever is already in your tab list.
