I went looking in the latest Opera browser on my Windows 10 system for a way to backup bookmarks. Alas, I found a way to import bookmarks but not a way to make a backup copy. I found an extension to do this but it says that making a backup of bookmarks is now part of Opera. If so, where is that, please?
BTW, my success rate at getting responses to questions here is zero. Please make this the exception.
