Taking off a star since a popup just happened in Firefox asking me to buy a kaspersky subscription. Annoying desktop popups are one thing, Firefox extension window popups in the middle of the screen during browsing are unacceptable. I will worsen the star review depending on the frequency of its appearance

Update:
3* now, kaspersky extension popups keep happening asking me to upgrade to a paid version

Update 2:
2*. idiotic popups noone asked for asking users to pay for a features that don't matter.
"x number of sites are collecting data" fake messages to make unknowing users worry for Nothing.

Update 3:
1*. how such intrusive "buy our product" tactics keep appearing left and right baffles me
