I have to add my opinion too.
My opera crashes (Ubuntu 14.04.3 LTS 64-bit) constantly after latest update.
I tried to reinstall it but no use at all. It even can't send crash report.
Somebody from developers has to check problem with Opera immediately.
Regards,

Hello.
As a experienced user previously working with Firefox and Chrome but not satisfied with develop situation where these two browser become more massive and slow, I decide to switch to opera.
I am using Ubuntu 64-bit so I DL Opera 30.
My configuration is:

Version: 30.0.1835.125 - Opera is up to date
Update stream: Stable
System: Ubuntu 14.04.2 LTS (x86_64; Unity)

I find minor problem in importing passwords from Firefox (import from Chrome is OK, tested on Windows platform). It do not import any passwords from Firefox at all. My latest Firefox version is 39.

Question: Does someone else have this issue and if it solved, where to find solution for this problem ?

Also, there has to be made significant work on PDF support of Opera, because existing one looks like is not finished or very poor done.

I use extension that call for Mozilla's JS in order to see PDF document. There must be better solution i suppose for PDF viewer.
