@burnout426 The hard part is that I would need to use that stripped version of Opera for few days until the loading get stucks. I use Lastpass constantly, so I would also have to start copy pasting all the usernames and passwords during that test. That means hundred of copy-pastes a day.
It is not consistent and happens pretty randomly. And like @ab-garcez said it also happens from different sources, like clicking link from whatsapp etc. I also noticed that If I close the problematic tab and re-click the link, it does not fix the issue. Sometimes waiting for few minutes can help and then the link is opening fine again...
I do not have Opera VPN enabled and Lastpass is only extension that I use. (beside the Operas own Ad-block).
