check if you have any updates waiting to install, UI>menu>settings>update
run a smart scan to see if you have any outdated apps
are you running a vpn, either avast or other as youve not mentioned which version of avast you are using.
No errors showing anywhere I have attached a screenshot of what happens in Firefox when I try to go to a website. No pending updates or running a VPN and anything else for that matter. I use Brave as my default browser and that get websites no problem. It doesn’t matter what site I try to go to either. It’s noting to do with a firewall either as I have made sure that Firefox is in the permitted group
OK Thanks for the replies but it’s working again now. There was a setting in Avast I hadn’t seen and now I’ve changed it all is fine and it’s working as it should
I had obviously at some point denied Firefox access for updates or similar as it was blocked in ‘Rule List’ ‘Application Rules’. when I removed the restriction it start working as it should
