The problem is that the links you have provided are actually not for two different subdomains. In fact, they are the same domain (<code>www.asna<!------>.ru</code>), just two different pages on that domain. While Firefox does treat two separate subdomains (for example, <code>www.example.<!---->com</code> and <code>admin.example<!---->.com</code>) as two different websites, multiple pages on the same domain will share the same saved logins because they are the same website. The reason for this is because some websites may allow users to login from any page on their website via a header or something of that nature. Tethering specific logins to specific pages of the same website would generally make for a bad experience when trying to log in. That said, you could still be able to save multiple logins for the same website, they will just both be displayed on both login screens. The only exception for this would be if both logins are the same username but have two different passwords. In that case, Firefox will think that you have changed the password for a single account and it will ask you to update the saved password. In that situation, a decent workaround would be to save your username with an additional character at the end. For example, <code>username</code> and <code>username2</code>. Then, both logins will be displayed for you to select and you will just need to remove the extra character once it's been filled into the login window. You could add this new login by adding the extra character on the login window and attempting to log into the website. Naturally, you won't get logged in because the username is invalid, but it should prompt Firefox to ask you to save the password. Alternatively, you can [[Add a login to Firefox Lockwise for desktop|manually create a saved login and password using Firefox Lockwise]]. Hope this helps.

Thank you!
