I’ve tried “help” and Google, but cannot find out why my Firefox browser at home does not gray out previously visited links. My copy at work does, and frankly I can’t tell where the magic check box might be located. Anyone?

Tools / Options / Privacy / Remember Visited Pages…

Mine’s set on 20 days, which I think is the default. After 20 days they go back to the unvisited colour.

Thanks. Although it seems fairly straightforward, I had my “Number of Days” set to zero. That, in turn, would not allow the “Remember Visited Pages” box to remain checked, after I checked it! So, I set it to “1 days” and now it does, in fact work. :smack:
