Memory Hog Bewertet mit 1 von 5 Sternen

Addons like this are why Firefox has a bad rep.
use the built-in error console for that. Click on Firefox > Web Developer > Error Console, or use Ctrl-Shift-J, to open it in the browser. Locate the filter at the top right and paste TypeError: can’t access dead object into it. If you see results, one of your add-ons is trying to access memory that has been cut by the browser.

Diese Bewertung wurde für eine vorherige Version des Add-ons (0.7.2.0) abgegeben.
