What are the ways to authenticate a firefox user?

Question

Information Security

There is one resource on which I do not want my 2 accounts to be linked.
Therefore, I plan the following action plan:
1. Do not use disk cache.
2. Delete cookies after closing the browser.
3. Read-only profile (in RAM, before opening the browser, update from the saved version)
4. Delete flash cookies before launch.
5. Naturally different ip.
6. Different screen resolution.
7. random time zone
I understand that I look like a paranoid, but it's more a matter of confidence than real necessity. Do not offer to use virtual machines.
The question is whether I foresaw everything, I heard about the method of determining using https tags
