Je suis nouveau !

Avast cumple su función de proteger, pero no megusta que frecuentemente quieran que uno renueve y pague nuevamente antes del vencimiento.

Good, apart from the tracking

This says it works with Firefox 48.0 or later, it doesn't.
I use Firefox 52.9 ESR on my old Windows XP machine, and the current version updated fine there but doesn't work, there's an extension icon but it doesn't do anything. Version 20.3.10 doesn't seem to work either. The last version which does still seem to still work in Firefox 52.9 is 20.2.501.
Please update your Firefox version requirements as it's misleading people at the moment!
Works great on the current Firefox versions on Windows 10 of course.

Way too many NAGS, promos and upgrade offers I don't want or appreciate! Ditto ALL Avast products...

Mouse over icons does not give tooltips in Google in both Firefox and Chrome. Also sometimes the page has to be reloaded to see the icons
