The Adobe Flash player is EOL for several years now.

Please explain the problem in detail. What does/dosn't happen? What are the exact error messages?

FredMcD, thank you for your reply. What does EOL mean? My specific inquiry is about web site's being able to identify me, or my computer. Does Firefox have any security protocols that can inhibit a web site from identifying me or my computer? Thank you.

EOL=End of Life.

Firefox 85 Cracks Down on Supercookies https://blog.mozilla.org/security/2021/01/26/supercookie-protections/

I use a cleaner (Bleachbit) to remove what it calls HTML5 cookies in Firefox. None are ever shown these days.

Hi Terry, thank you for your reply. Does removing HTML5 cookies from my browser make it so a web site either can't or has more difficulty in determining my computer or me? Does changing my IP address help the situation? Any suggestions? Thanks

Here's the short story if you block pertain cookies you will be restricted on site or get no access. If your doing nothing criminal or going to BlackSites then you don't have much to worry. What you should worry about is clicking on PopuPs or Adware that you don't know which is far worse in doing so you give them unfeatured access to your system and data without even knowing til it's too late. You should really go and read up on this on the Electronics Frontier site if your having this much worry about using the WWW. Going forward everyone user is going to have to give up some tracking to use the internet.

Dropa, Thanks for your reply. I guess bottom line, your not a advocate of removing HTML5 cookies or using beachbit. You made a prior statement, "Beyond a VPN or Proxy IP". I would presume using a VPN or proxy IP, (which I believe using a VPN is a proxy IP)?, might help or solve the problem I'm trying to accomplish? If I were to use a VPN which I presume is going to show a different IP address than my original IP address, that would help and make it more difficult to see my personal computer from one visit to the next on the same web site. Would you concur or am I all wet? Other than a IP address, how does a web site identify me, or my personal computer? Can you please explain, Dropa. Appreciate your help and patience. I'm not the most computer literate person. Thank you, Dropa.

Not saying it can't be done but there might be unintended network protocol issue if it happened. Some sites need cookies regardless to work correctly.

I never had a problem after removing them but, as I say, I don't see any listed in Bleachbit these days so perhaps Firefox isn't storing them.
