Starting with Flash 9.0.r45 the Flash plugin installer for Firefox and other Mozilla-based browsers does not copy any files to the browser plugins folder.

If it doesn’t, manually delete the “NPSWF32.dll” file from the browser plugins folder so that the newer version can be used. The installation of Flash 9.0 r45 or later should detect and remove the Flash plugin from the plugins folder of detected browsers. In such cases, the copy in the browser plugins folder takes precedence. If you see two versions of Shockwave Flash listed in about plugins, this can occur if the Flash plugin file “NPSWF32.dll” is located in the Mozilla browser’s installation directory plugins folder and another copy is detected in a different location, e.g., the C:\WINDOWS\SYSTEM32\Macromed\Flash folder on Windows XP. Note: To see the full path to the plugin file NPSWF32.dll as shown above, instead of just the file name, use about:config to change the value of plugin.expose_full_path to “true”.

For example, on Windows XP with Flash 9.0 r115 installed, you should see:įile name: C:\WINDOWS\system32\Macromed\Flash\NPSWF32.dll You can see what version of the Flash plugin is installed by entering about:plugins in the Location Bar of your Mozilla browser and finding the entry for “Shockwave Flash”. In other words, it’s possible to have the Flash 8 plugin installed for Mozilla browsers and the Flash 9 ActiveX control installed for Internet Explorer, and both will work. Each must be installed separately, since the Flash plugin installer does not add the ActiveX control and vice versa. There are two Flash players offered for Windows users: the Flash ActiveX control for Internet Explorer/AOL and the Flash plugin for Firefox/Mozilla/Netscape/Opera browsers.
