The problem I'm having is with cookie exceptions not saving. I've just updated to firefox 8.0 (desktop version), though I never tried to use the cookie exceptions function in previous versions. I have it set to delete my cookies when I close firefox. I've read that checking "delete cookies" in options -> privacy -> settings can override the other settings so I have it un-checked (everything else is currently checked). I've tried a variety of settings to no avail. Under options -> privacy I use custom settings, accepting all cookies and clearing the history when firefox closes - nothing else checked. Essentially, the only site that I use frequently enough to be bothered by changing the settings is google. I hate the instant search feature and I also turn off filtering. In any case, I set it to "allow" under exceptions and after closing firefox the settings are cleared. This also goes for sites that I block. I'm using windows xp, by the way. I don't have many add-ons that I use. The only semi-relevant add-ons are BetterPrivacy, for lso cookies and Adblock plus. Long ago I used TACO but I've had it disabled (though not installed). long story short, I add a cookie exception (to block or allow), close firefox, open firefox, no exceptions. Any help is much appreciated =)
