Installed version 31.0 from version 30.0. It would not display any web pages, e.g. google, had a message about not being able to connect. Did a Windows system restore point to version 30 (I had created a restore point before the install) . FF will now not save pinned tabs between sessions and it will not restore the last page from a previous session. All it will display is the Default FF page.

Can someone give me some idea's about how to fix this. I tried reinstalling version 30 but that did not work to fix the problem.

Some problems occurs when your Internet security program was set to trust the previous version of Firefox, but no longer recognizes your updated version as trusted. Now how to fix the problem: To allow Firefox to connect to the Internet again;

  • Make sure your Internet security software is up-to-date (i.e. you are running the latest version)
  • Remove Firefox from your program's list of trusted or recognized programs, then add it back. For detailed instructions, see

Configure firewalls so that Firefox can access the Internet. {web link}

You can check for problems with the sessionstore.js and sessionstore.bak files in the Firefox profile folder that store session data.

Deleting sessionstore.js will cause App Tabs and Tab Groups and open and closed (undo) tabs to get lost and you will have to recreate them (make a note or bookmark them if possible).

First, thanks for everyone responding. Here is what the problem was.... For some reason, there is a profile under Local in Mozilla and another profile under Roam. The Roam profile was the one that was being pointed to from the Troubleshooting tab under help. The local profile only had some partial files not including sessionstore.js. I copied all the files from the Roam profile to the Local profile. This restored the pinned tabs but not the open tabs from the previous session. I then updated Roam and Local profiles with the last sessionstore I could find in the Roam directory.... for some crazy reason this restored everything. Updating to FF v 31 was what initially caused this. I did create a restore point before the update, which would not connect any tabs to the internet (e.g. Google). I then restored from the restore point, and ended up with the damaged FF v30 installation, which would connect to the internet but would not pin tabs and remember them or display the last page I had visited as a start page....

So, I hope someone gets a chance to look at FF v31, and why there is a Roam and Local directory with profiles in them ?

You shouldn't copy files from Roaming to Local.

Firefox uses two location for the profile folder. The main Firefox profile folder with your personal data is in AppData\Roaming. The location in AppData\Local is used for the disk cache and other caches like the thumbnails on the about:newtab page and the phishing protection files as you can see by the folder names.

Did you try to delete all sessionstore-##.js files and sessionstore.bak?

You may want to leave sessionstore.bak-1024xxxx files with a time stamp that Firefox automatically creates when updating.
