I'm having the same issue with Opera. I have a new (July 2017) Windows 10 system with an i7 processor and 12gb ram. If I leave Opera open with as few as 3 tabs set to articles I'm reading or researching, I'll get Out Of Memory crashes on 2 of the 3 tabs, even if they're all from the same website. It doesn't matter if I have other programs open or not (Thunderbird is usually open). I don't have this problem with Chrome or Firefox. My previous system was Windows 7 with an i5 processor, and I don't recall ever seeing this problem. (both systems 64-bit)

RE: new version - OUT OF MEMORY issueOpera for Windows
RE: Couldn't load pluginsOpera for Windows
I'm running Opera 41 with flash ver.24 on a Windows 7/64 system, and I get the same "can't load plugin" message on many websites. Facebook will run some videos, but others only run a few seconds and then stop and won't restart. I have no problem running those same videos on Google Chrome, so the issue seems to be specific to Opera.
RE: Setting a theme as defaultOpera for Windows
I have exactly the same problem, and my version of Opera is also 30.0.1835.146, which was from an update it did itself.
I'm also having issues with tabs from the past opening when I start the browser. I changed the "startup" from continue from where I left off (my preference) to "open the start page", which eliminated two tabs from months ago, but after several re-starts, including after a computer reboot, when I went back to the "continue" option, a different tab from weeks ago opened up. Ver. 146 seems quite buggy.
