This new Opera is a mess. The flash plugin doesn't work, the "key" where it showed a stored username/password is gone and the browser wants access to my "wallet," at startup. Do I trust a new program that much? No way. I used to use Opera to play games in SWF, they don't work. Videos on Youtube? No, not any more.
Here are my stats : Linux Slackware64 ver 14.1
I can't even tell where the program is. I'm showing opera-12.16 under /usr/lib64 and another (version unk) under /usr/local/share/opera. It is true that a new version was needed but this one is not it.
