This is a simple add-on providing a button with the number of tabs in the current window. If you click it, a pop-up opens, showing the total number of tabs in all windows too.

Known limitations:
- The badge gets updated globally, so it cannot show the number of tabs in two windows at once. In inactive windows, the number of tabs in the active window is shown. If no window is active, it is the number of the last active window instead.

User reviews
It works well enough for what it is. But there are other addons on AMO that give more features. Most notably this lacks a preferences dialog where background/foreground colors can be selected which can be found in similar addons like 'Tab Count Icon by lllusion3418' or 'Tab Counter Wide by Jonathon Merz'. I also found the text to be smaller than the other 2 and slightly difficult to read (viewing from about 10ft away on a 50" TV set to 1920x1080); might be better on a pc monitor / different resolution.

Risk impact

Sum Tabs 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

Sum Tabs 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.
