If the XP computer HW would allow a newer OS you may get info about dual Boot and keep the XP if you need to keep a Java configuration.
If it's just a warning on Java or something else, and there's no need about it, just search for the needed software, backup all your data and then Upgrade the OS.
@fairyvearth You can just copy the speed dial from your Other speed dials folder to your Speed dial folder in Bookmarks, that's easy. What isn't available is any way to make them stay in sync in the future, if you will still be using both devices.
@nycticorax It's called Chrome Sync API and, for what I could understand, it's for accessing Google Sync services and store your data using your Google account in Google servers.
Opera doesn't use it.
I have the same issue with sync in my mobile browser or pc browser
I think the problem from your ISP banned opera services or the problem from opera browser account and account settings
I have the same problem: server error. I'm trying to pass the bookmarks of my old smartphone to the new one and the only thing I can do is to have hundred of bookmarks saved in my old computers all together. I'd like to organize alla my recent bookmarks as they were in my last smartphone, but it' s impossible. I'm thinking to use another browser.
