TabAlert от Maxfield Lewin

Are you a tab power users with hundred or thousands of open tabs in your browser at any given time? Have you ever had to restart your browser because too many tabs were loaded into memory? TabAlert will keep you informed and out of the danger zone by telling you how many of your precious tabs are currently loaded.

With a configurable Green/Yellow/Red alert system, you tell TabAlert how many tabs your machine can handle. Then keep track by glancing at the color coded extension icon, or enable an optional badge with an exact count.
