hi @avl, thanks for your efforts.
I'm using extensions:
Dashlane - Password Manager
Install Chrome Extensions
but have tried disabling and uninstalling all extensions (so none are present whatsoever) and the problem is still present.
i've tried reinstalling opera severals times but get the same problem.
it is the same whether i use the beta version or the standard version too.
I have noticed that youtube is where the vast majority of the crashes happen, and too a lesser extent on instragram.com. this makes me wonder whether it's related to video files? although
it is like there a certain trigger words almost. a few weeks ago i searched a term on youtube and the page crashed. if i try that exact term now it still causes a crash. if i try a different search, chances are youtube works fine.
