No icon or blocking in Firefox. All adguard settings are default other than me adding filters. Like i said edge seems to be fine got the icon and blocking checked on Google.com (saw the icon) now using edge for youtube to block ads as i type.
Installed apps so far:
Spybot Anti becon - blocks windows 10 tracking etc
Sandboxie (though im not currently sandboxed)
Lastpass (firefox extension)
It "may" fix its self when i have restarted, thats something i have not done yet... Never thought of that till now so will see in the morning and report back then.
