RE: Are Speed Dial tiles being forced on us?
But the extension issue was a definite issue (not just for me) that was fixed, was it not (I still haven't seen it in months)? Also, I've seen several people mention the SpeedDial problem, so it shouldn't be unique to me but could still be a problem (if it's not a feature, which it sounds like you're confirming it's not).
Note that when I remove the Speed Dials in question (had to do it just today, which is in line with it tending to happen a few days after a new build), they stay gone for a matter of days. It's not as if I remove them, close Opera, run Opera, and see them again, which would certainly suggest the writing problem you mention. I can also add SD's consistently. So I don't think it's that. Maybe it's the signature issue though.
-Current Win10 build: 17686.1003. But it's happened with all the builds I've used stretching back to last year. Including 17134, which is an RTM build.
It's different from yours. What does being on a blacklist mean? Maybe you'll see something in it. I see that it contains all six of recurring items (Overstock used to be the seventh, but it must have been dropped).
