Spurious speed dial weather extension wont remove
Windows 10 64 bit
Since updating to 45, an additional speed dial extension named "yo.no" has appeared on the speed dial start page. Clicking Remove temporarily deletes it but then appears again the next time the start page is accessed.
I've tried disabling all extensions, checked that I've not a bookmark or anything related to Norwegian weather (or any weather!) and restarted Opera each time but to no avail. I just cant seem to get rid of it - permanently.
