In searching, I see something for Chrome about typing "thisisunsafe" in the window when you get an error where it adds an exception for the site.
Don't know the details about that, but maybe it works in Opera too.
i have switched to firefox as opera does not have smooth scrolling support for linux. even chromium or chrome doesn't. it looks like only ff is the Saviour for linux. it was good going with opera. I still love it. but the jerky scrolling is a deal breaker for me. so long. love u opera.
@leocg Oh but can you still add high performance so the browser will use more cpu ram and gpu for very high end PCs i got 16gb of ram and a intel core 6 gen i7-6700hq, nvidia geforce gtx 1060 6gb vram, 128gb internal ssd, 1tb internal hdd.
Pretty much if you like how Opera does things but want to be able to change you default search engine in the speed dial page then perhaps you might like to use Vivaldi as apparently they'll let you do it without a problem
