Features & Capabilities

lefred’s GroupKeep helps you save your Firefox tab groups and restore them whenever you need them.

You can save the active tab group or all tab groups in the current window, then restore them later in the current window or in a new one. Saved groups can be renamed, searched, deleted, exported, and imported.

When Firefox Sync is available, GroupKeep uses Firefox’s built-in synchronized extension storage so your saved groups can appear on your other Firefox desktop installations connected to the same Mozilla account.

Features include:

• Save the active tab group • Save all tab groups in the current window • Restore groups in the current window or a new window • Preserve group titles, colors, tab order, and collapsed state • Search saved groups and tabs • Rename and delete saved groups • Export and import JSON backups • Synchronize saved groups through Firefox Sync • Fall back to local storage when Sync storage is unavailable

GroupKeep does not use analytics, advertising, remote code, or external servers. Saved tab-group data remains in Firefox storage and is only synchronized through Firefox Sync when enabled.

Is lefred's GroupKeep 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.

lefred's GroupKeep requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details

Critical Grants access to browser tabs, which can be used to track user browsing habits and history, presenting a privacy concern.

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.

lefred's GroupKeep is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
