Are you talking a Addon or standalone? If standalone FF doesn't mess with Kaspersky itself.

I had Kaspersky for years and only the most recent "upgrades" have been eliminating it. That's why I am refusing upgrades.

Updating Firefox doesn't remove Kaspersky. I have Defender and updates has never remove this A/V. I think something else is going on. So how are you doing updates?

I stopped updates the second time FF removed my Kaspersky's.

Still refusing upfdates for same reason! TY.

Something just doesn't add up here that it would remove Kaspersky. Neither program should affect the other operation or installing.
