@doctorowl They are probably part of a page you've visited, that's why they are on the cache directory.
Do you have the start page with news enabled? maybe it could be related to the ads displayed there.
This all is a bit hard to understand, but looks like you are accessing your local sites by IP? You could create entry in hosts file, associating your IP with some DNS name (better would be use DNS itself - routers should be able to assign some name for itself and other devices) and access your sites by this name and configure Opera for this name. If your IP changes, you only have to reassociate it in hosts file (or in DNS service).
Yes!! :))) You did it, mr Wonderboy! You solved it. Thanks ever so much! You saved my day. Now I do:
cd C:"Program Files"\Opera
launcher.exe --disable-web-security --disable-site-isolation-trials --user-data-dir="c:\insecurebrowserdata"
And it works again as before. Can't believe how lucky I am :). It's indeed a Chromium issue: I tried Chrome and it's exactly the same thing. I feared that the guys at Opera had disabled this OH so useful feature.
@mgeffro Thank you for providing the explanation. However, I am still not happy with enforced permissions. I would rather have the pop up and the choice to choose and to remove Google any time I wish. Period.
That's his question - why doesn't Android have it?
Keep in mind though, "Do not track" is almost meaningless. The website gets decide what it will do if it sees a "Do not track" header, and many just ignore it.
