I just finished scanning using Secunia.
When I use Secunia Online Software Inspector (OSI), I received the same result as yours: Firefox 3.5.2 with X (insecure).
You can report it to Secunia on the issue at their forums (free registration is required) : http://secunia.com/community/forum/
But when I use Secunia PSI (the desktop version and free also from Secunia), it detected Firefox 3.5.2 as "patched".
A little confused. On Aug 3rd there was an update to mozilla firefox to 3.5.2 which you could download through the check for updates which I did and everything was/is fine. When I ran a scan at secunia online software inspector this is what it is showing.
Mozilla Firefox 3.5.x Mozilla Firefox 3.5.x 3.5.2 Mozilla Firefox 3.5.x
This installation of Mozilla Firefox 3.5.x is insecure and potentially exposes your system to security threats!
The detected version installed on your system is 3.5.2, however, the latest patched version released by the vendor, fixing one or more vulnerabilities, is 3.5.2.
Installed on Your System in:
C:\Program Files\Mozilla Firefox\firefox.exe
I have never had that before. If I posted in the wrong place or something forgive me. Running windows XP sp3 Anything I should do???? Thank You Sandra
