odd port numbers used by Firefox

Veröffentlicht

Hello Everyone, I looking through my firewall logs I see that Firefox uses port numbers like 64862, 64864 and others. Does anyone know what these ports are used for? My firewall is blocking them and I cannot open it up until I know what they are.

Best Regards

That seems to be Firefox connecting with itself, perhaps for reasons related to process isolation.

Hilfreiche Antwort

On Windows Firefox will use some (random) ports to communicate with the software security device. That are local connections that do not leave the computer. I don't know in what range these ports fall.
