Great news for Firefox users, we could finally implement Firefox 3.x support into AM-DeadLink.
AM-DeadLink 4.1 will fully support FF3 dead link checking, downloading FavIcons is however not possible. When you select “Firefox 3.x” in the main toolbar, you’ll be asked to close Firefox 3.x, it’s not possible to scan your bookmarks while Firefox is running.
We have now uploaded a first beta, please provide feedback if you experience any kind of problems.
