Yesterday, Mozilla released Firefox 3.6. If you’ve updated your browser, your Herdict add-on may have broken. We’ve created an update to the add-on to fix this.
Go to Tools>Add ons.
In the extensions tab, right click on the Herdict add-on.
Select Find Update.
If you don’t currently have the Herdict add-on installed, you can get it here. The add-on allows you to report sites directly from your browser (without going to herdict.org). The sheep icon also changes color depending on the site you’re on, so you can get a sense of if the site you’re viewing is inaccessible to other people in the herd.
