Upgrading to Firefox 3.5 has introduced an issue with Spybot Search & Destroy that didn't exist before. I notified them of this (modified version follows) but they refer me to you (very Microsoft-ian of them, isn't it?). Just FYI, this issue also affects the latest release of SpywareBlaster.

In any case, you might want to look into this...

//BEGIN
Leaving "Site Preferences" checkbox checked in either of these places in Firefox 3.5:

1) Tools | Options... | Privacy | Settings...
2) Tools | Clear Recent History...

results in the Firefox immunization protection offered by Spybot Search &
Destroy 1.6.2 (cookies, images, installations, and popups) being wiped out. In the case of 1) above, the problem occurs simply by opening the Firefox 3.5 browser. In the case of 2) above the problem occurs when choosing to clear recent history (Ctrl+Shift+Del) in Firefox 3.5.

Unchecking the Firefox 3.5 "Site Preferences" checkbox in the places listed above resolves these issues -- but at the expense of me having to accept the possibility of site preference data being preserved within Firefox.

This problem did NOT exist until the installation of Firefox 3.5. I have the latest version of Spybot Search & Destroy with the latest definition files
applied, and both were in place and functioning perfectly with the version of Firefox (3.0.11) I had in place prior to upgrading to FF 3.5. In fact, Spybot S&D has worked fine with all versions of Firefox prior to 3.5! The problem started immediately upon upgrading to Firefox 3.5. The result is a potential compromise to Firefox security.


Reproducible: Always

Steps to Reproduce:
1. Verify that all Firefox immunization/protection offered by Spybot Search &
Destroy 1.6.2 is in effect; close this program.
2. Open Firefox 3.5
3. Verify that the "Site Preferences" checkbox is checked in Tools | Options...
| Privacy | Settings... (if not, check it and restart Firefox).
4. Close Firefox.
5. Repeat Step 1, which will show that all previously enabled Firefox
protection is now disabled.
