Thanks everyone! It was the adblocker wreaking its usual havoc. All good now. Appreciate all who took the time to answer.

On some websites, sign-up buttons do not show at all. I have to go to Chrome to find them. One example is this page on the HGTV site here

There should be a box to add my email to enter the sweepstakes, but it is completely missing in Opera. Help, anyone?

I just switched over from Chrome and so far am loving Opera. But every time I try to make a call using Google Voice, a box pops up saying the website wants to access my microphone and asks if I will allow it. I click "allow" but nothing happens. I had no trouble making calls in Chrome. The Google Talk plugin is installed.
