Hmm, what kind of "system restore" was it? Do you mean the feature where you roll back a set of recent Windows updates, or a full restore of the OS which wiped out Firefox and required you to reinstall it?

Note that using System Restore can cause your Firefox installation to get corrupted because only white-listed files are restored. *always be cautious with using System Restore. *you may lose data in the Firefox profile folder like .js and .ini files *you may need to reinstall affected software Best is to backup your profile folder before doing a System Restore. Try to rename/remove the <b>xulstore.json</b> file in the Firefox profile folder with Firefox closed. You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the <b>about:profiles</b> page. *Help -> Troubleshooting Information -> Profile Directory:<br>Windows: Show Folder; Linux: Open Directory; Mac: Show in Finder *http://kb.mozillazine.org/Profile_folder_-_Firefox ----- Make sure toolbars like the "Bookmarks Toolbar" are visible.
