Sum Tabs Firefox

Sum Tabs

By: Timvde
Adds a button with the number of tabs to your toolbar

Features & Capabilities

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.

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.

Is Sum Tabs 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.

Sum Tabs requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details
