Does it work with vbulletin ? Rated 4 out of 5 stars
I got the following error adding a vBulletin foum search box - Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [mozIStorageConnection.beginTransaction]Is it impossible to work with a site that requires you to be logged in ?Great idea anyway. Saves having to go through Mycroft to find search plugins.
There's a Wiki of the error message at http://helpful.knobs-dials.com/index.php/0x80004005_%28NS_ERROR_FAILURE%29_and_other_firefox_errors
