One of our internal applications has a flash object on a page. I need to test one of the corner cases when there is no flash plugin available/installed in the browser: n
Found it, there is an another switch which tells chrome not to load external plugins at all:
--disable-plugins-discovery
Disable discovering third-party plug-ins. Effectively loading only ones shipped with the browser plus third-party ones as specified by --extra-plugin-dir and --load-plugin switches.
By combining --disable-internal-flash
and --disable-plugins-discovery
I've achieved disabling all flash plugins in Chrome.
