That did the trick! Thank you for your help.Hello,
I have same problem but with google suggestions (whipses) at Firefox browser.
When I have a Adguard turn on, google sugestions doesn't work. BUT, I remember that before I install HTTPS certificate, google sugestions work.
Therefore I add "google.com" to I dont know as say it in english but it can be something as whitelist for HTTPS filter at Adguard. This whitelist it at same menu as Instal HTTPS certificate to Firefox.
Now all work fine.
Last word: I am so soory for my english.
