Firefox has automatically updated to version 113.0.1. When it opened my previous tabs had all been closed to I selected the restore previous browsing option. Tabs all loaded with no problem. however none of the tabs could access the internet. I've tried removing Firefox from my Bitdefender fire wall and then restarting Firefox. Bitdefender automatically adds Firefox to the allows list but still won't access the internet. I opened a new tab and typed "Google.com" and got the message "open network login page" telling me I need to login in to the network to access the intenet. My PC is connected via ethernet and I use Nordvpn. I have disabled both Bitdefender and Nordvpn but still cannot access the internet with Firefox but can do so using Brave. I have accessed the Setting in Firefox and changed the Network settings to no proxy. Can you help please?
