Why is firefox sending so many outbound connections, close to 200.

Posted

When I first open Firefox, everything slows down and/or stops. When I check my firewall, it occasionally shows as many as 215 outgoing connections, as much as 95% of which are from Firefox. The OS is Win Vista Home Edition. The firewall is Comodo.

Hi,

Please check if this repeats in Safe Mode. Safe Mode disables the installed extensions and plugins in Tools (Alt + T) > Add-ons.

Please also note that Firefox may open multiple connections per server, so having many tabs open could also be a reason. Firefox may also prefetch content from links in a page while idle.
