YES i use AdGuard for Android For several years now, I've never had a problem I had to remove FireFox and I use Chrome or Microsoft Edge with no problem at all nor Samsung internet browser

Okay. It could be that AdGuard is causing this issue. You may wish to make sure this is up to date from the Google Play Store.

The other tip I have been pointed towards is setting Firefox for Android as the default browser to force Android to handle traffic to it correctly.
