Hello all,
I've just sent the following lines to Lukas.
***
I think I've found the explanation:
I use Roboform which (in a certain configuration) does not attach to Firefox 39.
I've changed (with Resource Hacker FX) the version in firefox.exe from 39 to 38, and thus Roboform works properly.
Prior to v2223, Avast wouldn't try to prevent the change, and also there was no difference between running the the original firefox.exe and the new modified one.
With v2223 , Avast tried to prevent the change (I chose to exclude). Also, when running the new modified firefox.exe - it consumes an extra 20 MB on start-up.
Interestingly - adding "firefox.exe" to Settings -> Exceptions, solved the problem (no extra 20 MB) for that session; but after reboot it's there again: a difference between the original file to the modified one.
I'd be grateful for a solution.
(I'd be glad to send you the dump files if you still think it might help).

Best regards.
