I seem to be having an issue with Opera portable over different Windows versions.
Here is the issue I am having. I am running Opera Portable on my Windows 10 PC, but I also have Windows 8.1, Windows 7 and Windows 8.1 Ent. installed on external SSD drives. As with Firefox portable, I can just backup my entire Firefox portable installation over to my backup drive, then as I switch over to each different Windows version, I can then copy the main FF backup over the existing one. Therefore, all my FF versions are up to date. It is not so with Opera. If I take the entire OperaPortable64 folder and copy it over an existing one, then I have to login to every site again. I also make a backup of the "Cookie" file, but this doe snot solve the problem.
Can someone please tell me what I am doing wrong.
Thank you very much in advance.
