So, in the next day or two, I plan on factory resetting my computer, and I want to see if there is a way to transfer things like bookmarks, currently open tabs, and other stuff along those lines so when I reinstall Opera GX I can continue exactly where I left off. Any light shed on this topic would be helpful! Thanks!

So a while back, I noticed that YouTube was no longer completely co-operating with Operas dark mode the 'light' is only visible when the video scrubber thing is pulled up, as it isn't part of the video. It can be fixed by using YouTube's own dark mode, and excluding it from opera, but I want to know if there is a way around that solution. Thanks either way!
