Yeah I'm having the same issue. I reinstalled windows from scratch and if I leave Opera open too long my whole computer freezes. It was doing it in an earlier version then they fixed it and now it's doing it again. SO FRUSTRATING!
An small clarification:
Sleep and Hibernation also works with AC Power, it's not just intended to work with battery only, but High Perfomance Power Plan doesn't go to Sleep or Hibernation.
Just Power saver and Balanced Power plans has Sleep and Hibernation enabled.
If I compare information on my Asus laptop (the one with problem) and Acer desktop computers it is almost identical when using Opera://gpu
And I'm sure I have the latest available drivers installed.
It could be somthing about Asus hardware/software that is not working well with Win 10 or Opera 33, but I really don't know.
The problem started after latest Windows 10 update, build 10586, thats for sure.
I having the same problem as well. Anyone know how to update portable edition manually?
Just run the online installer again. If it doesn't recognise that you are using a usb/standalone install, just change the install method.
I used to have my boomark folders placed in the bookmark bar at top of screen. After re-installing Windows 10 I had to install Opera again. I imported my Opera bookmarks from a usb stick to Opera. That is no problem.
Then I mark "Show bookmarks bar" (top of screen), and I will drag and drop my bookmark folders to that bookmark bar. But the folder will not stay put when I drag them to bookmarks bar. I have done this many times earlier without problem, but now it won't work. Both my desktop computer and laptop have this problem now.
Currently you cant move the tab bar in Opera 32. You might look into an extension that can do it (remember you can also make Chrome extensions run in Opera) but I don't think its likely. As for all the settings, you can find them in the settings page and Opera internal pages (opera://plugins, opera://flags, etc.).
an antivirus that interacts with your browser is pointless on android.
any potential malware would have to go through the package installer to install itself, which is where it's already checked by any antivirus you might be running or the "verify apps" feature of the Google play services.
