Same here, dear... the latest version of Firefox.
Hmm... I don't know why it doesn't happen for you, I get the same results each time I try it.
I usually click on the search box in the upper right hand corner and then it opens another page with the large search box in the body, and that is what I use to search. I wonder if that could also be part of the reason I get so many nonworking links... You suppose that could be a contributing factor? Could be something to consider, I guess.
I'll search as you have suggested and see how it goes, it would be great not to get so many broken links. I'll give it a go and report back if it improves my search results and minimizes the nonworking link issue.
You do a great job as a forum moderator and you're a good teacher as well. Thanks!
