Spaces

Intuitive tab management. Spaces is a workspace manager for the browser. It treats each window as a unique space and lets you name and save each one. You can close a window full of tabs at any time and reopen it later continuing where you left off.

Features & Capabilities

Spaces keeps track of new tabs opened in each workspace and also tabs that you close. It also allows you to quickly move a tab that you are currently viewing into any other space whether it's open or closed. Great for when you find yourself opening a tab out of context with what you are currently working on and want to come back to it later.

Find you have 50+ tabs open? Do you abuse "Bookmark tabs..." for session management?

Spaces was developed to help users that tend to keep way too many tabs open. It encourages you to move tabs that are not immediately relevant into a different, more appropriate space - thus removing it from your current window. This keeps your browsing session manageable - both visually and from a memory perspective.

Isn't this essentially just bookmarks with folders? Yeah, pretty much - but you'll want to use it.

Is Spaces 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.

Spaces 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.

Spaces may not be trust-worthy. Avoid installing if possible unless you really trust this publisher.
