Hi cor-el,

thank you for your reply and sorry the delay. its strange but I not receive the mail notification for your answer, with other 3d I become the notifications. sorry. now I leave this tab open in firefox, refreshing the tab from time to time ;)

ok, this evening I will try to put (not only google.com) but youtube.com + facebook.com too in the Allow window of Exceptions.

(its strange that until FF25 --with the "new" yt -google+ service) it was enough to add google.com as cookie exception, remaining correctly logged in after firefox shoutdown, and I did not need to customize again and again all my yt personal settings like login, video window size, Annotations, country preferred...)

I will try your suggestion this evening and then I reply to you. At the moment I warmly thank you.

If you need further information about the Troubleshooting information page, please read the article Use the Troubleshooting Information page to help fix Firefox issues.

Thanks in advance for your help!

1) @cor-el: no, I allowed the exceptions cookie: the same behaviour. Login required. All personal setting lost in youtube :(

2) @Waka_Flocka_Flame here the log that you required. thanks in advance for investigating. No idea what went wrong after upgrading to FF26. Surely FB and YT/g+ cookies are involved, no idea what changed during the change ff25 (and all previous version!) > to ff26. thanks for helping. regards.

LOG (I guess that this log is the same as in ff25):

why I dont receive email notifications from your site? in the past I received all your notifications. I did not click on "Stop email Updates".

https://accounts.google.com/ServiceLogin?uilel=3&service=youtube&continue=https%3A%2F%2Fwww.youtube.com%2Fsignin%3Faction_handle_signin%3Dtrue%26app%3Ddesktop%26feature%3Dredirect_login%26hl%3Dit%26next%3D%252Ffeed%252Fsubscriptions%252Factivity&hl=it&passive=true

here the url with login for youtube. In the past I was able to see here my subscriptions.

while on FB, the box "Remain logged in" becomes unflagged at FF startup.

with the exception of the correct Session restore (!) and your forum (!! still logged in after reboot too!!), the behaviour is (fast) the same as when i checked in the past the box "delete browsing history" to let the file sessionstore.js to become smaller in size. its strange.... at least youtube should work well when I re-open FF, because the customization process is too long for me, to be performed every time a open FF. thanks for investigation. should I file a bug on bugzilla?

up...

re-up...

Firefox has more privacy and anonymity options than other browsers. Check your privacy settings and cookie behavior very closely and make sure you are not using the private browsing function or the do not tracking

Hi, I setted as allowed google.com and youtube.com. even i UNcheck Delete cache and cookie!!! I dont understand because from ff8 until ff25 all went fine , I was always logged in when opening the browser, when I updated to ff26 I need 2 minutes at browser restart to get my personal setting in youtube. Yt (very annoying) and facebook, While this forum is ok, I remain looged in even if I close ff. Very mysterious...
