Opera doesn't keep setting?
After shutting down Opera then reopen same day no reboot or next day after computer reboot Opera has lost it setting.
Download location changes
show the bookmarks bar
Extensions all missing
and so on....
I just updated to Opera 20.0 so don't know if will get some problems
Why Opera not saving setting?
CCleaner might be the culprit. Are you using its latest version?
Check if there isn't anything avoiding Opera - Hard to see any software bugging Opera.
Just unstalled CCleaner Have now reinstall, I hope this has fixed.
[Test]just shutdown Opera then reopened bookmarks bar and setting still there
Just got to reboot computer finger crossed.
