Opera 26 is a disaster. The nice, sensible bookmark management of V12 and earlier is gone. The import to v26 just created a jumbled mess. The info I had put int eh notes fields for bookmarks is completely gone.

How do I revert to V12 before I just dump Opera all together.

I used Opera as my main browser on Win and Mac for a very long time (10 yrs+), but this v 26 seems to have dropped features in favor of cuteness.

When I click on a link in an email in Mac Mail, the link opens in Opera by overwriting the open window, rather than in a new windows.

For example, I am looking at a page in Opera, I switch to Mac Mail to view a new message that has a web link in it. When I click on the link, the page opens in place of the page I was viewing in Opera, instead of opening a new tab. Opening a new tab was the behavior in Opera in Windows (I just switched to Mac.

Can I change this so that a new tab opens?

This is my configuration:
Opera Version 12.16 Build 1860
Platform Mac OS X System 10.9.2
