This is becoming a nuisance. Hard to believe that I'm the only person facing this. It's happening on another computer now. I have to execute searches twice. After the first search I have to close out the blank tab that it generated and then execute the search again. 90% of the time it works the 2nd time but I've had a few occasions when I needed to do it 3 times.

A switch to Chrome is looking like a probability.

Yes, I have the exact same issue. I get a blank tab the first time I do a search with Yahoo, and I have to close out the tab. I redo the search, and the second time it goes through.

Definitely a Firefox issue because it happens even when I change my search engine.

Hi,

I'm really sorry you experience that. This issue is being investigated under bug 2034019.

To be short, it seems to be Yahoo blocking some Firefox configurations. A mitigation should follow soon (unless Yahoo fixes it on their side earlier).

Thank you for responding. However, I'm not so sure it's Yahoo blocking Firefox because when I switch my search engine from Yahoo to Google (but retain use of the Yahoo home page), it happens in that configuration also.

There's some updates, I'll be sharing them in https://support.mozilla.org/en-US/questions/1574298

Hi,

The issue should now be resolved on Yahoo's side (which means you don't need to change any settings to make it work). Could you please confirm?

Yes it hasn't been happening now for about 3-4 days. Thank you.
