Review for 100 Search Engines for Firefox by KJPH
Rated 1 out of 5 stars
I was very pleased with this add-on, it gave you many more useful links than others. But somewhere along the line of FF updates this add-on stopped working. Even the support site doesn't seem to work anymore. I would welcome reactivation or a good alternative.
