@Slightly-Salty Just use Firefox.
I migrated the majority of my things over, and only use Opera for very specific needs that Firefox can't manage without Workspaces (Or an equivalent feature).
If you don't need that, then FF is a lot easier to use, and more customizable in the way you're asking for.
