I didn install the Acrobat plugin for Mozilla, so why is it using it?
Mozilla’s plugin scanning is locating another copy of the Acrobat plugin, using either the Acrobat plugin scan, or the Netscape 4.x plugin scan. Mozilla configuration files may need to be edited with a text editor that supports Unix line endings, such as Wordpad. Do not use Notepad to edit configuration files. To disable the Acrobat plugin scan, open \default\pref\winpref.js, and comment the following line by adding // to the start. pref(“plugin.scan.Acrobat”, “5.0”); To disable the Netscape 4.x plugin scan, open \default\pref\winpref.js, and uncomment the following line by removing the //. //pref(“plugin.scan.4xPluginFolder”, false); Note that this will prevent any plugins from being detected using the Netscape 4.x plugin scan, not just the Acrobat plugin. More information about plugin scanning. Note: In recent Mozilla builds, you will need to edit \greprefs\all.js instead of \default\pref\winpref.js.
