Firefox won't update. It downloads and says 'unable to verify the integrity of the incremental update', so it downloads the complete update package

Firefox won't update. It downloads and says 'unable to verify the integrity of the incremental update', so it downloads the whole version. But this doesn't work. Even if I download using Safari it won't install.

See http://kb.mozillazine.org/Installing_Firefox#Mac_OS_X ..... Download a new copy of the Firefox program: http://www.mozilla.com/firefox/all.html Trash the current Firefox application to do a clean reinstall. Install the new version that you have downloaded. Your profile data is stored elsewhere in the Firefox Profile Folder, so you won't lose your bookmarks and other personal data.
