Y! Mail becomes more usable with the extension installed, but I prefer using a different search engine, in particular, I like Google's specialized searches, like the one you get when you search for a song.
There is a greater concern, however. I have had trouble with security on a company managed machine and lots of reports for unapproved activity. Mostly when I use Yahoo Mail. I have so many when the extension is enabled, that my account is locked.
I had no time to investigate more deeply which kind of requests come from the extension, but as a precaution I have uninstalled it completely.

Great plugin, but really irritating that uninstalls it self !

Yahoo se fout vraiment de la gueule de ses utilisateurs !!!
Comme pour de très nombreux internautes de part le monde, cette extension se désinstalle toute seule !!
Dire que cela est irritant est un euphémisme !
2 ans sans mise à jour...je crois rêver !!

Yahoo really doesn't care about its users !!!
As with many internet users around the world, this extension uninstalls itself !!
To say that this is irritating is an understatement!
2 years without update ... I think I'm dreaming !!

good

Addon isn't working!!!!

I like it when it works. It disappears after a few days and Yahoo sends a message saying "Goodbye, sorry to see you go".

don't like changes life is already too
compicated...
