@vivaldi_browser I really like your browser but I really struggle to use this browser due to the constant crashing, especially using youtube. I feel like I’m on my wits end because it just constantly crashes over and over even just trying to mess with the settings.
Ublock Origin uses a noticeable amount of resources. It may be that your computer just doesn’t have enough RAM to run it and heavy sites like YouTube at the same time.
Vivaldi itself is slightly heavier than “plain” versions of Chrome and Firefox because of all the UI stuff, so it could be exacerbating the issue.
I’d suggest confirming this by opening the task manager alongside the browser.
