Web browser cannot open attached file by associated application

WinXP Pro SP3 32bit
Comodo 3.8.65951.477 (free version).
Browser: Mozilla and Opera.

When I click to a link to zip/doc/torrent etc. file in my browser, I’m asked: “save to disk” or “open with”.
If I select “Open with” I receive the following message:

c:\temp*.* could not be opened because an unknown error occurred Try saving to disk first

I can save the same file to disk and then open with the corresponding application, but it’s too annoying.

Before Comodo installation everything worked properly.

This problem was reported by some other users 1, 2, but no solution was found.

How are your settings for Opera and Firefox in D+?

Try a clean install of the new v3.9 that just was released: https://forums.comodo.com/feedbackcommentsannouncementsnews_cis/comodo_internet_security_3976924507_released-t39202.0.html .

Opera and Firefox were treated standardly: as WEB Browser.

I’ve deinstalled 3.8 and installed 3.9.

The problem is fixed in the new version.

Thank you!
