Worked Rated 5 out of 5 stars

Fresh install of FF, no other addons, worked to fix broken IdenFavIcon. I only run a few other addons, primarily xmarks and lastpass and adblockplus. In the many years I've run those addons, they've always played nice with all other addons.

This user has a previous review of this add-on.

If you figure out which other add-on is causing the problem, I could check if I can fix it easily.
