Comodo Firewall 2016 save webpages problem

Hello.
I have some problems since I installed Comodo Firewall on my PC - Win7x64 SP1, Chrome x86 browser.

  1. I cannot save webpages like I use to. You know - saving an article, a recipe, a medicament prescription, etc.
    Chrome shows me that it saves 54%-60% of the page, than… nothing. Stucked.
    I looked into settings, Chrome is on “trusted”.
  2. More than that, uninstalling Comodo Firewall got it worse, it messed up my LAN settings (broadband) and also the LAN driver. Re-installing it made the LAN card to work properly, also the “WAN” problems in Device Manager (caused by the same uninstall) dissapeared.

Thank you.
