Firefox Support Forum

Hi, Firefox 67 recently automatically downloaded onto my Mac computer that uses High Sierra. Since it downloaded, when I quit Firefox and then reopen it, it no longer restores my previous sessions even though it is checked in my preferences to do so. I have to start all over when I open Firefox and this is the first time this happened since I have been using it for over 15 years. What can I do please? Thanks.

I have Windows 7 Ultimate 64-bit PC.

Start Firefox and open up 4 tabs with different websites for each tab.

With the 4th tab displaying, close Firefox

Wait until all instances of Firefox in Task Manager have ended

Restart Firefox

The restore previous session loads the 4 tabs but does not display tab 4 being the last tab showing when closed. It displays a blank page and is totally unresponsive. Starting a new tab (5) is also unresponsive. Yet the other 3 tabs work fine.

Steps taken – uninstalled Firefox and deleted existing profile then reinstalled Firefox with a new profile but no change. No add-ons, bookmarks, history or settings changed.

Please help.

I woke my laptop up from sleep. I am using Microsoft 10 64 bit. Firefox auto updated, my computer restarted, I lost all of my tabs. A whole pile of them. I've always been able to restore session, or restore previously closed windows, etc, but all of those options are greyed out. I went through and cherry picked a few of the web pages I recognized out of my history, but many of my tabs have stayed open for quite some time and are not in that history. How do I recover my tabs?

Been happily using firefox for months now with same privacy settings:

History:

- Use custom settings
- Clear history when firefox closes -> settings: all except cookies checked

Cookies and Site Data:

- Accept cookies, Keep until Firefox is close
- In Exceptions I've got bunch of sites with allowed cookies

So, normally all cookies except allowed ones have been cleared on firefox exit. But now for some reason cookie exceptions list disappears on exit.

Something I've already tried:

- It happens when all extensions are disabled
- deleted permissions.sqlite

Any ideas?

When I close Firefox on Windows, and then run it again after some time, is opens my last viewed page. I don't want this, I unchecked the option in settings, I even edited about:config and this is still happening. It is making me crazy and I am using Firefox for one day only, and will come back to Chrome if this keeps doing this idiotic thing.

How to turn the option for good?
