Also updated to 42.0.2393.351 on archlinux - opera still crashes when trying to download.
Disabling [Ask where to save each file before downloading] option allows me to download affected files from the websites. Please be so kind as to not remove this option.
With thanks & kindness.
Thank you, dude! It fixed the problem while I tried to open any file in the browser (under Ubuntu)
Faced this problem almost every day, it's awful trouble. Anybody knows how to set preffered applications for MIME file types? I suppose it would fix the problem, but I couldn't find any MIME settings in Opera
So your old version of Ubuntu doesn't support that. It's not unusual to see messages like that when you open Opera from a terminal as not all versions of Linux support the same features. As long as Opera actually works as expected you can pretty much ignore messages in the terminal.
He was really asking about the menu bar as far as the Bookmarks menu, Opera 42 doesn't have a menu bar.
You can still download Opera 12, but it wasn't built for modern Linux systems. I mean, from the file dates 12.16 is over 3 years old. But it is still on the FTP server if you want it.
Address bar? If you don't want suggestions then turn them off. Go to Settings, type "prediction" in the search box, then clear the checkbox for "Use a prediction service to help complete searches and URLs typed in the address bar".
