Should Adguard Assistant icon show on all web pages?
I am using firefox and adguard is set on proxy mode. Only about 20% web pages show the Adguard Assistant green icon at the right bottow.
Is it normal?
No, it's still several months out until it lands in beta. Probably a couple more months after that until it lands in stable. I wouldn't expect to see the CoreLibs-integrated version until the end of the year.
Like I said, I'm sure the AG support and dev teams would be very interested why automatic mode doesn't work for you.
But then again, ETAs and whatnot seem to be a jinx.
