I had no problem with these links.

There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connection certificates and send their own.

Hi missolga, I don't know where those gray icons are coming from. Does one of your add-ons modify search results with "reputation" information? It looks a bit like the Kaspersky "K" -- does that sound like it might be the source?

I believe kaspersky may be the source but i wanted to check with all possible sources.

Hi missolga, it's certainly possible that a Kaspersky add-on or Kaspersky intermediary (web filtering feature) works a bit differently with different browsers. If you think their software is inconsistent between Firefox and other browsers, you could check their support or forums to see whether that is the expected behavior or whether there could be a configuration issue in Firefox.

I recognize it from the bad ol' days when I had Kaspersky installed ....
