I'm using Opera as browser. I can remember that in the past, when I googled a restaurant, I could dial the phone number right from the search results.
Now, I see in the title bar
tel:<number>, but the dialer doesn't open.
In addition, I just noticed that an
ebay:// link does also not open the Ebay app but does nothing.
Any idea what I have configured for achieving this behavior? And even more interesting: how can I restore the original behavior?
