Doesn't work for me also But it's supposed to!!!!I hope alwill is gonna fix this soon
Since I'm an avast Home user, I can't say for certain if the Pro version - Script Blocking will work or not with the Mozilla browser, however, if Mozilla isn't in the list of browsers were you can enable script blocking,
Extract from avast Help file:
avast! - help: resident protection
Resident Protection: Script Blocking - Protected Programs
Select the web browsers you want to enable the script checking for.
Possibly for the future, Alwil could look at incorporating the script blocking into or as an add-on of Web Shield (for Pro users?), then browser dependency might not be an issue (if web shield worked with a browser, so should script blocking)?
Just how this would be achieved would obviously require someone much smarter than I
