Features & Capabilities

When installed in Firefox, YATS adds a quick tab switcher you can open from the toolbar or a keyboard shortcut. Type to fuzzy-search across your tabs and related sources, then press Enter or click a result to go there.

Open tabs — Search all open tabs across windows, including tab group names. Results are tagged with colored badges for the source window (when multiple windows are open) and tab group (using the group's actual color).
Closed tabs — Optionally include recently closed tabs (session restore).
History — Optionally search browsing history as you type.
Fuzzy matching — Subsequence matching with scoring (consecutive characters, word boundaries, and cross-field matches like group + title).
Smart tab focus — Optionally return to the previously active tab when you close the current one (MRU behavior).
Session hygiene — The switcher popup is kept out of “reopen closed tab” history

Actions

Open / close switcher: Ctrl+Shift+Space (macOS: Control+Shift+Space)
Navigate results: ↑ / ↓
Activate selection: Enter or click
Close switcher: Esc

You can also click the YATS toolbar icon. To change the shortcut, open about:addons, use the gear menu, and choose Manage Extension Shortcuts.

Settings

Open the gear button in the switcher footer to configure:

Which sources to search (open tabs, closed tabs, history)
Whether closing the active tab should focus the last-open tab

Settings are stored in browser.storage.local and persist across browser restarts.

Is YATS - Yet Another Tab System Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

YATS - Yet Another Tab System requires a few sensitive permissions. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

YATS - Yet Another Tab System is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
