An automatic update ran this morning. Noticed when I started up the computer, a message came up saying that Firefox was running, even tho' it wasn't. Update finished, and now I cannot get the search tool to work. Help!!!

Is this the search bar on the about:home page/
Try to reset some preferences to the default with the SearchReset extension:
Note that the SearchReset extension only runs once and then uninstalls automatically, so it won't show on the "Firefox > Add-ons" page (about:addons).
If there is a problem with searching via the default about:home page then try to reset the search engine used on the about:home page.
Reset the browser.startup.homepage_override.mstone pref via the right-click context menu to the default on the about:config page and close and restart Firefox to restore the about:home page to its default.
- Open the about:config page via the location bar
- Type in the Filter bar: mstone
- Right-click the browser.startup.homepage_override.mstone line and select: Reset
- Close and restart Firefox
If this didn't help then delete the delete the chromeappsstore.sqlite file in the Firefox Profile Folder and repeat the above.
You can also check for problems with preferences and try to rename or delete the prefs.js file and possible numbered prefs-##.js files and a possible user.js file to reset all prefs to the default values.
Also check that you do not have a mozilla.cfg file in the Firefox program folder.
