This update really ticks me off. I was upgraded to version 5 without any warning and all my tabs are gone. They had all my logins on them and there are too many to remember. What the *^%^*&(*)()(*&. How can I restore back to version 4 and my tabs.

Just as a check that you are in the same profile as before, check if you have your own bookmarks and not something supplied to you as a very small sample. Bookmarks sidebar is Ctrl+B

If the menu bar is not present, click on "Alt" to bring up the menu bar] Click on the History menu then on "Restore Previous Session" then also through the History menu click on Recently Closed Windows, then on Restore all windows.

Sorry that doesn't work. It keeps bringing up start new.

If you are in the profile manager then that is probably your problem, starting a new profile would be devoid of your old information. You have to find the profile you had before the problem, and use it (or copy it into your new profile, if you are beta testing and need to use multiple profiles) . Generally anything you do in a profile must be done with Firefox down. If what you are looking at looks like the picture in

but more than just default, first find the correct profile you need by find the profile used until the date of the problem, check each profile for the last modified dates for places.sqlite and the .json files in bookmarkbackups in your profiles.

Since you are on Windows 7 as am I, you can get there by inserting your username that you log in to Windows with. The foldername in the Profiles directory includes the profilename plus additional characters to prevent two profiles from every having the same name on your system.

C:\Users\<userid>\AppData\Roaming\Mozilla\Firefox\Profiles\

When you identify the correct profile, choose that profile name in the profile manager, then click on "Start Firefox". Never delete any profiles unless you are sure of what you are doing and have a backup of everything on an external device.


You can add the profile to your Desktop or Quick Launch button so you won't be asked, once you are working properly.

Some information on how I set up my Windows 7

This is the second time that this has happened. The first time I did a System Restore and everything was back to normal. This time, however, no such luck and no alternate profile to go back to. Even looking into the History did not provide much help. I'm at the point where Firefox will cease to be my browser of choice. These unannounced updates are a real hassle. Even M$ gives you an option as to what patches to apply and when.

I've also discovered that my NoScript settings have been compromised as a result of the most recent upgrade.
