"YAAAAWN! Do we really need to do this 'I hate new Opera' over and over again? As leushino says the new Opera is here to stay so either live with it or move on to another browser."

Are you kidding? It is not a matter of hatred, the matter is that I (and it seems that I am not alone) liked Opera 12.17 and I don't like Opera 24. As for now, Opera seems to be just the elder brother of Chrome. But if I wanted a Chrome-styled browser, I'd download Chrome, not Opera!

Now, I don't want to offend anyone. Chrome 24 is more reliable, and I can't deny that; I don't have to reload the pages several times before actually see what I am browsing for, and the notifications on Google+ are displayed properly, as example.
Yet, I can't help but to wonder whether or not a better browsing experience could have been achieved without losing pretty much everything of the old Opera, this is just what I am asking. And, if you think all of those who think as me to be haters, feel free not to comment, I won't be offended by your silence.

Half of time Facebook doesn't load; I have to refresh the page to make it actually work.
There is the website of an italian transmission, it's called "Servizio Pubblico"; the videos they upload don't show. I don't know whether or not did they change something, because, after several failed attempts of watching vidoes, I eventually gave up.
Youtube has rendering problems: when I skip to a different moment of the video, the player has to reload the entire video before playing what I requested, even when I skip to an already loaded point.
4chan sometimes do not load correctly, same goes for Facebook: there is a white layout and the various links appear in a vertical column, I can't describe it properly without a screen, though.
This is what I can think as for now, but I am sure that there are some more.

I've been using Opera for several years, and I have always loved the way it let me customize fully, yet with ease, almost everything about internet navigation.
Now, I decided I had enough of Opera 12.17 (too many pages did not load correctly, problems with YouTube and so on) and updated to Opera 24, with a lot of faith in the new, awesome product I was going to download.
And I can't find words capable of expressing how completely disappointed I was; in 2 years since last release, it seems like not a single step forward has been done. And I really hope someone proves me wrong, that I simply misunderstood the browser or downloaded a fake version.
Of the many things that bug me, though, a minor one is really irritating me for some reasons: the tabs are not semitrasparent (the ones in Opera 12 were); does someone know a way to change this...? I don't know, skin editing, an extention, whatever allows me to still have a little shred of the old Opera feeling. Thanks for the attention for a nostalgic user.
