Firewall blocking Firefox

Today avast asked me to update firefox and I did. After the update however Windows Firewall blocked Firefox, after reopening firefox the popup didnt come up again. Im not sure if I should be worried or not but i posted logs for any help. Thanks

Nothing apparent, are you having any problems ?

No but it happened on my brothers computer as well Windows Firewall blocked some features of Firefox, I can post a screenshot if it helps?

Yes please

Could only get one from my brothers laptop

I believe the reason for that popup is that you are using FF on a public network, is that correct ?

Yes it is.

OK then you have the option to allow FF through the firewall for public networks, it is a protection facility of windows firewall

Ok thank you.

The latest firefox update included Firefox Hello, A new commuication tool that requires access to the public firewall rules.

Hope this helps.
