My firefox crashed, but when I rebooted, one of my windows had Yahoo.com on all of the tabs, not the original content. I tried restarting firefox multiple times and could not get the tabs back. Now I can't get the windows back either. I've lost all tabs and windows. (Originally about 6 windows of unfinished/unread work) Any suggestions? I've tried repeatedly to do a Restore of previous backup but it doesn't restore the windows, just the bookmarks and toolbar.

You may have several issues.

First, your System Details shows;

Installed Plug-ins

Shockwave Flash 11.5 r502 Shockwave Flash 11.4 r402

Adobe PDF Plug-In For Firefox and Netscape 11.0.0 Adobe PDF Plug-In For Firefox and Netscape 11.0.03

Adobe Shockwave for Director Netscape plug-in, version 12.0.2.122 Adobe Shockwave for Director Netscape plug-in, version 11.5

Having more than one version of a program may cause issues.

Flash is notorious for not cleaning out the older version as part of an update. Grab the uninstaller from here: Uninstall Flash Player | Windows Uninstall Flash Player | Mac Then reinstall the latest version.

Shockwave Flash v15.0.0.152 http://get.adobe.com/shockwave/
