I have the latest version of Norton Internet Security on a Windows 8.1 computer. Firefox version 36.0 works fine. Version 36.0.1 is blocked by Norton. I reset the firewall per Norton's instructions but that did not help. I reverted back to Firefox ver 36.0 but every time I restart the computer, Firefox updates itself and I am back at square one. Does anyone know how to fix this?

Norton showed where to exclude things from Autoprotect Open Norton Administrative Settings. Under Performance Monitoring, find Program Exclusions. To its far right, press the Configure + link.

You will have to add each program one at a time from the Mozilla Firefox and Mozilla Maintenance Service<Windows> folders..

Fix problems connecting to websites after updating Firefox For Norton specifically it looks like it manages its updates differently than other antivirus/firewalls: https://support.norton.com/sp/en/us/h.../v84115070_EndUserProfile_en_us?q=Norton+firefox+windows+8+update

Mozillazine also had a reference to this from a long time ago, it may be out of date:

A more recent solution from another user was to change the Firewall settings from auto to Firefox and Firefox addons: question/1048513
