If like me you are unfortunate enough to have colleagues that use the propriety features within Adobe Acrobat, such as digital signing, you eventually end up having to load Adobe Acrobat Reader on your beloved Mac. While telling Acrobat that it should not be the default application did stop it from being the default viewer for PDFs held in folders, Acrobat unilaterally decided it should replace Preview as the PDF viewer plugin in Safari and my other browsers. To remove the Acrobat browser plugin, I went to the folder /Library/Internet Plug-Ins and deleted any files that mention Adobe and/or PDF in the name. Restarting Safari, I had Adobe-free browsing again!
