Directly after the update to Firefox 43, some users who have the third-party Nvidia Forceware Network Access Manager firewall software installed on their computer might observe some new problems, like Firefox crashing on startup or as soon as you attempt to load a page over the network. Firefox 43.0.2 users may not be able to load websites anymore - all pages may stay blank or show Server not found errors when users try to connect to them through the network.

Affected users should download and install the latest version of Firefox or uninstall Nvidia Forceware Network Access Manager from the system to solve the issues described.
