It's very weird and I feel not safe having this scam websites added as CSS injection in my pages source code. I see porn website URLs everytime I do some debugging, or I have to display ads... of course I can deactivate the ad blocker on sites I am developing on, but still a very strange dilemma.
Thanks for your help @leocg

I have the same problem under VirtualBox
Today I searched the VirtualBox bugtracker for my - as I guess - related problem, because VB throws an exception and kills the running machine (Host Win10, guest Solus), whenever I close Opera. Sometimes even when I close a tab, but I've had no Opera lags with my current settings that time.
I found something with a suggested workaround (to avoid the crashes) that told me to disable the checkbox in the VB settings which switches the 3D support on. So I did.
Result: no more crashes, but the annoying lags again.
@bwall said in Location issues:
The Opera 48.0 Help page says
Settings > Preferences > Advanced > Network and uncheck "Enable automatic redirection".
But there is no such option!
Can you please tell me how exactly have you found this help page that says that? I am trying to reproduce but I don't see it if I open Help from within Opera 48.
Where I do see such suggestion it is on old Help pages for Opera 12 (Presto) - but you have to google that page up...
Thank you for the support and tips.
All you were right: one extension was leaking the real IP by WebRTC. For my surprise was "Privacy Badger" of EFF.
This extension set "Use default public network interfaces only" as default. In this option de real IP of ISP leaks.
For curiosity I also tried "Use default public and private network interfaces only" and "Use any suitable network interface (recommended)". Both leaked my ISP's IP and local router IP.
Thank you a lot!
@garypen Well I have tried it in the past (about a year ago) but mainly I don't like the forced Windows 10 look of it and I'm used also to Opera's method of creating thumbnails for the Speed Dial items, although I liked a lot that in Vivaldi you could have as many Speed Dials you 'd want to, contrary to Opera where it gets confusing and untidy if you have many. It shouldn't have any peformance problems (I found this also http://www.digitaljournal.com/internet/op-ed-vivaldi-s-new-version-1-12-browser-worth-trying/article/505723 confirming it), and its bookmarks method in a tree amongst many other things are more on the classic path of Opera Presto or Firefox.
