Private Browsing mode sometimes doesn't remember cookie info when opening links in new tabs

Posted

Also, when in Private Browsing mode, and I go to view the cookies in Options -> Privacy, I can see the cookies from the normal non-private browsing mode. All of them. It's not a fresh, clear, list like it should be.

I don't think any info is being read or recorded between the two sessions types, though. Just that sometimes, when opening a link in a new tab or window, it forgets the cookie information. Again, this is in Private Browsing mode.

I never had this problem until I upgraded to Firefox 19.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

  • Do NOT click the Reset button on the Safe mode start window or otherwise make changes.

Question owner

The problem is still there. In safe mode, when I go into private browsing mode, if I go look at the list of cookies, I can see all the cookies from the non-private mode.

Any progress or additional information yet?

I also can see all of my "normal" cookies after switching to private browsing. (I remember that in the past I would see only a "blank" window when first switching to private mode.)

Yes, I have tried safe mode and disabling add-ons, with no change in this behavior.

Add-ons I have installed:

Adblock Pluss 2.2.3 BetterPrivacy 1.6.8 Ghostery 2.9.3 Googlebar Lite 4.9.7 IE View 1.5.6 Microsoft .NET Framework Assistant 1.3.1 PrivacyChoice TrackerBlock 2.2 Status-4-Evar 2013.02.16.23 Bookmark Favicon Changer 1.74 (disabled) CheckPlaces 2.6.2 (disabled)

Thanks!
