I also submitted many tickets to support staff but got no reply from support staff..
As said in the confirmation e-mail message you got after have filled the bug reports - most of them without needing by the way as several reports about the same thing are not helpful - there won't be any reply unless necessary.
Opera mini 7.1 for symbian works quite well but opera mobile 12 for symbian doesn't.It can only access some websites (default speed dial) and It always shows a "network error" page when accessing other websites.Even it can access google.com after trying a few times.It is very great due to supporting html5.Hope that it will be fixed soon
I tried opera android v.21 doesnt work too. Then update to v.29 and thats working till now but 1 missing features is i cant download youtube directly from opera.
But other tube website still working & can be downloaded.
Ussually i use site: savefrom.net in pc/laptop, but opera android didnt worked.
I now understand, its google itself blocking using old version. Yah bussines struglle i think.
Opera is most android browser i use, still can work with 50 tabs opened no lag (if u have big gb space internal).
I surely missed feature for save to .mht file that can be open in pc. hope opera will added that offline savefile features
Seeing the enormous amount of attention this has grabbed (!) ..err, me too. (syncing bookmarks over from android, even better - I'd even settle with all my stuff from an ye olde symbian copy, beats nothing!)
