nfl.com and other

Hello Opera. I am disappointed. I use this browser for few years now and I love everything about it but its growing unreliability.
What I write here is from some 10.xx version (with Opera, I am scared of updates! Every update fixes something and breaks something), 11.52 version and I've also tested 12 alpha version and it is all same.
So. NFL.COM, fantasy section - you just can't use Opera, as soon as you get to your team it starts to refresh page like crazy (11.52 and 12a; 10.xx just crashes there I think).
vkontakte.ru Photo uploader - multi photo uploader never works for me, I have to use its simple variation. I also get some distracting errors when I use search for music or video there.
I had some problems with file uploading on mail.yandex.ru (right now works fine), on multiphoto.ru (today at morning - had to upload every photo separately) and I think it's enough for now.

I think Opera is the best of the best and I've always recommended it to everyone, but not these days. Now I have to start other browser (that actually works - it works without any trouble and I haven't updated it for months btw) every day and as the time goes I tend to think more and more that it's maybe better to have 1 OK browser than 1 OK browser and 1 that-you-used-to-love-but-those-days-seem-to-be-gone browser.

I've just checked, problems with live on Unibet.com that I was writing about more than a year ago are still there (you have to press "submit" button over 9000 times). If Opera Team doesn't care I think I will jump ship very soon.

P.s. I'm sorry for rant and grammar and too-many-letters and stuff if that offended someone, it's just that Opera is not a tool for me, but more like a friend. And I'd really, really would love to save our friendship. It's your turn now, Opera team.
