What can you do against identifiers?

My laptop showed me this. Could it be an error message from Firefox or should you take this message seriously? Has anyone logged in to me (what I'm assuming) or what happened there?

What exactly is the error message? And when was it displayed? Did you just open a program or did you set something?

I have "activity tracking" on Firefox and can look in at any time.

Where?

Do not understand your problem

With your Forefo account?

Do you mean this?

Yes, exactly that!

And what exactly do you mean?

4. Display from the left.

My 2 answer if you mean that

This is google

If you only use firefox it's a good thing

Because Chrome does that and then gives it to the NSA

Tip: Use DuckDuckGo

I have Google & Firefox…

NSA… So so.

And not with DDGo?

YES

Oh yes all browsers except firefox and waterfox make calls with the NSA

I tested it myself

Yes, definitely…

Try it out for yourself
