@leocg Thanks for the help.

I started a thread about the source of an unknown icon appearing in the sidebar.

The topic was deleted by leocg with this comment and link: This topic has been merged into More ads despite opting out?

Clicking on the link returned this:
Not Found
You seem to have stumbled upon a page that does not exist.
This is not helpful and is certainly no way to respond to a legitimate question about what might be malware. Can we please try again?

Opera: up to date OS: both Win 8.1 and 10
This icon just appeared in the last day or so. There is no info (tootip) when hovering over it and there is nothing associated with it in the sidebar setup. I reluctantly clicked on it and received a message saying javascript must be enabled for the app to run. I have JS disabled by default and I'm not inclined to enable it to see what this is.

Anyone know?

I don't know if the previous two posts are directed to me or the OP. If to me, I understand that the QNAP cannot be accessed while in Turbo mode, just as I understand why Turbo allegedly exists (I have a metered connection). I made the suggestion in case the OP had Turbo enabled for perhaps the same reason as I.

I have to turn Turbo off in order to connect to mine (just in case you have it on).

26.0.1656.60

Loading a pdf in Opera works as expected until you switch tabs. Going back to the pdf results in a frozen page that must be reloaded for functions to be restored.

@ho72 You can turn Turbo back on. Today's update should have fixed your printing issue

No, it did not. Version info: 26.0.1656.32 - Opera is up to date

That did it. Thanks.

Just create an outbound firewall rule to block autoupdate.exe (or whatever it's called). Disable the rule when you want Opera to update at a time of your choosing. Note that when the update is complete, you'll have to update the firewall rule as well because the update executable will now reside in a different folder.

As I pointed out in my thread that was closed,

I'm using Opera 25. Will look for Opera 26.

EDIT: Opera 26 now installed, get this message: Opera does not include the PDF viewer which is required for print preview to function.

Found a PDF viewer extension but installing it made no difference.
