Hi, not with the program itself just with a scanner, 1 out of a couple which can be disabled. Also they fix issues so could be fixed.

There is also : Avast/AVG, Kaspersky, BitDefender and ESET that intercept secure connections and send their own certificate or scanners blocking.

More information inside than just the name :

Oh, and all the AV/Firewall makers have a Forum where can go to find the work around to fix the issues.

What do you mean Firefox #6 release? the current version of Firefox 61.0.2.

Your anti-virus will run in the background regardless of whatever browser you have. However, McAfee is generally regarded to be a poor anti-virus. I suggest just using Windows Defender, which is already on your computer.

Either way, Firefox will run just fine.

Tyler Downer; I am not familiar with Mozilla Firefox versions. The number #6 was taken from a search. Although with another search release 40 , release 5.0 and release #6 are shown. Thanks for your input. -John-

Hello tanskysr,

If you decide to start using Firefox (and you won't regret it if you do), you can download the latest release version (in your preferred language) from here :

https://www.mozilla.org/firefox/all/

And what Tyler Downer said about anti-virus : so true  !

yes, please use the link McCoy gave you, that will guarantee you get the latest version.

Let us know how it goes!

Thanks for all your help -- John --
