Manage plug-ins
Plug-ins add more functionality, but they also increase the memory needed
and security risks. To minimize memory requirements, you may want to install only the plug-ins that you use. To load a plug-in correctly, you must place it in the plug-ins folder. You can temporarily disable plug-ins when starting your software.Disable a plug-in
Do one of the following:
- (Windows) Open the plug_ins folder (Program Files\Adobe\Acrobat 9.0\Acrobat\plug_ins).
- (Mac OS) Control-click the application icon, and choose Show Package Contents. Then double-click the Contents folder and open the Plug-ins folder.
- (UNIX) Move the plug-in out of [location of install]/Adobe/Reader9.0/Reader/plug_ins.
- Select the plug-ins you do not want to load, and move them out of the folder. Some of the plug-ins may be in folders nested inside the plug-ins folder.
Disable all plug-ins temporarily
- Press the Shift key immediately after starting Acrobat.
