The tabs I have open show as new tabs rather than the websites I had opened.

I have a large number of tabs open in a window, and when I hit "restore previous session" to open them, they are shown as "new tab" rather than the websites I had opened. Prior to the previous two updates, I had no problem with this, but now it's a recurring issue on Firefox.

Make sure that the history and possibly the disk cache are working.

Do you see the history in the History Manager (Library; Show All History)?

To see all History and Cookie settings, choose:

  • Tools > Options > Privacy > Firefox will: "Use custom settings for history"

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

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).
