firefox installer creates inbound rules?
I noticed several times firefox inbound allow-connection rules created in windows firewall after installing firefox new versions. I want to know if this is done by the firefox installer. Thanks, Dan
Additional System Details
- User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2272.76 Safari/537.36 OPR/28.0.1750.40
The firewall has to update the permission for a new version of Firefox, otherwise communication would be blocked because the application has changed.
One or a few versions ago, some plumbing was added to allow Firefox to connect to videocasting devices and I think that was why Firefox wanted rules allowing it to discover those devices on your local network (or advertise to those devices perhaps). I edited those rules to block* and haven't noticed any ill effects. Later updates didn't change the rules.
If you want to block the connections, switch the rules instead of removing them:
Windows 7 Start menu > Control Panel > System and Security > Windows Firewall > (left column) Advanced Settings
In the dialog that pops up: Inbound Rules
Then double-click the Firefox rules and change to Block one by one.
