<![CDATA[Built in PDF viewer does not open pdf document]]>I am using opera version 66.0.3515.27 and when I am trying to open a pdf nothing is happening. If I click the save button, the pdf is being downloaded as usual.

Refresh the "Download PDF files instead of automatically opening them in Opera" option, restart opera, clear cache, but nothing changed. Reset to default made Opera to open pdf using the embedded pdf viewer for 2 days and then the same symptom.

I have to admit that by removing the googletm-translator, the problem was removed! I am testing it all day today and it works fine

Try IMTranslator.

Test in that Opera but don't enable Opera Sync, don't install any extensions, don't enable VPN and don't enable adblocking.

Does it work there at least?

It doesn't open pdf anymore in Opera. I have to download and to open in Foxit Reader. When I want to print directly from Opera (attached pdf in email, open -> print) it doesn't see the document.

Digging a little using the Developer mode, I found that there is an error. Opera is trying to load favicon.ico icon and the server returns error 401 (Unauthorized). Can this be disabled?
In some other cases the favicon.ico is not found and the server returns the below error.

Resource at '/favicon.ico' not found: No resource found
Cannot serve request to /favicon.ico on this server

"Off topic Tip"
Follow the Signature's BackUp | Reset link.
Take the opportunity to start a Backup plan, even create a Template Profile.

SyncBack | Synkron helps.

Windows 7 (x64)
Opera Test profile | Opera Back up | Reset
