Why is Firefox unable to access the internet each time there is an update?
Each time there is an automatic update, Firefox no longer is able to access the internet. I get the "unable to access" error. I then uninstall it and use IE to open the internet so I can access Firefox, download it and install it again. This happens every time there is an update. My firewall settings are fine.
Some firewalls automatically block a browser if they detect a change (update) in the installation and it can take time before the firewall receives an update that recognizes the new version.
Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full, unrestricted, access to internet for Firefox and the plugin-container process and the updater process.
Re: Why is Firefox unable to access the internet each time there is an update?
I agree with cor-el as the most common reason for Firefox not being able to connect (on Windows) after a update or new install is due to the software Firewall blocking the new version .exe yet it may be allowing the previous.
