It is a shame that FF is lacking of any session management option for a long time and hate multi tab support and addons and that like mix plus give to FF great value in the past...and would in future, but now it is going to die as top layer maybe only as engine will survive.

Mozilla FIREFOX have you just totally ABANDONED your users?

THIS is why I HATE your updates, and hit "dismiss" for them again and again--and then you go and upload your "upgrade" anyway!

One of your recent ones--in June--not only REMOVED "Restore Previous Session" as an option but STOPPED my browser totally from "SAVING OPEN TABS"--so when you re-started your precious browser with its "upgrades"--you lost EVERY DAMN ONE OF MY TABS--and I had about 30 open--and have NO WAY of recovering all of them!

Another recent upgrade (early July) made Facebook not open correctly in Mozilla--did just fine on Chrome or on my phone.

Tonight I allowed Firefox to upload its new "upgrade."

It LOST ALL MY TABS AGAIN when it re-opened--and "RESTORE PREVIOUS SESSION" was not a visible option in History.

I fortunately had deliberately saved all the tabs I had open (in a WORD document), so I put Firefox in "Safe Mode", and tried to fix the problem (which does NOT occur in "Safe Mode.")

AND NOTHING HELPED.

At least Facebook works now.

BUT I WANT TO SET MOZILLA FIREFOX TO SAVE MY TABS AGAIN!!!!!!!

AND YES--- I DO have the following two choices on the "General" area in Settings checked: Open previous windows and tabs Open Firefox automatically when your computer starts up

BUT NEITHER SEEMS TO BE WORKING.

MOZILLA you just don't give a damn about your customers any more, do you?

At one time in the past, I could PERSONALLY CONTACT a customer service person by email / chat who could help me fix the problem.

No more.

I have no idea how to get Mozilla Firefox for Windows to go back to SAVING MY TABS or putting "RESTORE LAST SESSION" back in my History options.

If you do care about keeping me as a Mozilla Firefox client, PLEASE POST A SOLUTION FOR THIS PROBLEM! Or PATCH your updates to FIX this!

If not--well, I really really HATE Chrome, but I guess I'll have to bite the bullet and learn how to use it--since CHROME at least does NOT lose my tabs!!!
