@leocg When I open a new tab (Shift + Speed Dial item) , Opera closes the current tab. Previously, I could use Shift + Speed Dial entry and have as many tabs open as I wanted. Now, I can have only one tab open at a time.
I've found the Add Tab feature workaround, but using it is a tedious pain in the neck.
Thanks for your help.

How come I can only open one tab at a time in Opera? Can't find any way to change the settings for Tabs.
