Firefox 1.5 and higher will make a backup of your bookmarks though I have never read about any official feature. I use separate profiles for each version of Firefox. This is where my bookmarks backup file is located.

Yours will be located under something like...
C:\Documents and Settings\Administrator\Application Data\Mozilla\Firefox\Profiles\Firefox 1.5\bookmarks.bak

Change the administrator username to whatever windows username you are using. Secondly change the profile name (my profile's folder name is "Firefox 1.5" in example).

Hope this helps.

Thanks for the reply John however in both my user name and also "all users" there is no folder called application data!

I had bookmarks of all the admin panels etc etc I really need the information!

Can't be this simple but you never know!

You may have "Do not show hidden files and folders" selected.?

Go to C:\Documents and Settings\your_user_name

On the top menu.
Go to Tools.
Folder Options.
Click on the View Tab.
Select Show hidden files and folders.

You should now see the Application Data folder.

Also even if you do not have hidden files and folders enabled if you correctly type in it's name in the address bar at the end and hit enter it will still open.

As long as you have the address bar enabled on folders ;)

appi2, You are now my hero of the day.

No idea why it wasn't switched on I use hidden files all the time. Anyway, after clicking through to my user name I find the FireFox folder > Profiles > and instead of having firefox 1.5 or something mine reads: "ir65z2xq.default", Clicking onto Bookmarks.bak and also bookmarks.html has nothing in them (empty bookmark files).

Very strange that everything is normal appart from the bookmarks, history, passwords and everything else is the same as normal.

So still, nothing.

Anything in your C:\Documents and Settings\<username>Application Data\Mozilla\Firefox\Profiles\ir65z2xq.default\bookmarkbackups directory? There should be five days' worth of backups in there.
