The Web is a vast sea of information. Many a time, we find ourselves following hyperlink after hyperlink, quickly overwhelmed by the ridiculous amount of tabs in the browser. This is where a tab manager can make life easier. Tabo allows you to save all currently-open tabs as a session. This session can then be loaded to open up the saved tabs in a new window. Now, you can safely kill tabs with the luxury of visiting them only when they are needed once more. With that, my only hope is that Tabo brings you peace of mind when browsing.

Pretty much exactly what I was looking for. If it doesnt crash a bunch like other tab managers I've used after a week I'll come back and give it a 5. Also it'd be cool if you could manipulate individual tabs in the window. Super cool tho still.

It's a shame you can't close any of the listed tabs.

Minimal and fantastically clean UI and UX. Hoping to see this addon continue to develop. In particular I'd like to see a confirmation or 2nd UX action required before Clearing All sessions, to avoid accidental clicks destroying history.

Risk impact

Tabo requires some risky permissions and may not be safe to use. Exercise caution when installing this add-on. Review carefully before installing.

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, bypass your security settings, and access your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Risk likelihood

Tabo has earned a fairly good reputation and likely can be trusted.

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 Browser Add-ons, 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, especially ones with higher risk impact and/or higher risk likelihood.
