I agree, Opera is getting to be more trouble than it's worth. Seems every time it is working fine and I get it configured the way I want it, there comes another upgrade and I start all over again. I have used it since being a paying subscriber (#2 I think), but I am getting tired.
So Opera 26 loaded yesterday. My imported bookmarks come up as big, splashy icons taking up huge real estate so I have to scroll way down to get to what I want. Where's the file menu? Where are the developer tools? This thing is useless. I uninstalled it. When you stop supporting 12, I'm outa here.
