Having both installed, I had trouble with Firefox. I could not logon to one of my bank accounts, using FF, win 7/32. What happened was that the click on the logon button was registered (dimmed) but no logon. Using Chrome I could logon.
Apart from that I also got a false positive detection error from F-secure regarding WSA
So I decided to continue the trials without an already installed package (but kept windows firewall of course)
=== edit, removed the screendumps from my cloud

If you choose to "allow the application" on that screen from them, do you receive subsequent errors? Also, was the error before or after the bank account issue? I'm curious because if you hadn't allowed WSA through F-Secure yet, that may have been where your issue was occurring.
Unfortunately I do not remember whether the Firefox issue was before or after allowing WSA to execute.
