I want to disallaow installation of external plugin like Adobe Shockwave
I have to disable many options and features in Firefox ESR, i play with the about:config and file.cfg. But I didn't find how to lock or disallow the installation of tiers/external plugin like Adobe Shockwave, with an execution with an install.exe on Windows.
Thank's a lot.

Thanks guys but i found a solution here : https://superuser.com/questions/168354/how-can-i-block-new-plugins-from-installing-on-mozilla-browsers-to-prevent-inst
I use this section : you can try setting plugin.scan.plid.all to false in about:config. This disables firefox registry-based scanning for new plugins
It was for Firefox ESR 60.2.0, on Windows 7 and 10.
have nice day!

What's your computer system and Firefox version?
The Flash Player is a plugin. You can disable it by; Type about:addons<enter> in the address bar to open the Add-ons Manager. Hot key; <Control> (Mac=<Command>) <Shift> A)
On the left side of the page, select Plugins. Find Shockwave Flash, and select Never Activate
You could also remove the player using these links;

That was very good work. Well done.
That only prevents Firefox from finding the Flash plugin via a registry scan. There are more locations that Firefox scans for plugins.
Did you verify that you aren't able to install the Shockwave Flash plugin by creating a plugins folder in the location that Firefox uses for the main profile and copying the plugin file (NPSWF64_##_0_0_xxx.dll) to this plugins folder?
- C:\Users\<user>\AppData\Roaming\Mozilla\plugins\
When I try to install the FlashPlayer plugin, the install path is : C:\Windows\System32\Macromedia\... There is nothing in %AppData%\Mozilla\Plugins.
So that why I use the "stop scan" of registry key.
Quote: There is nothing in %AppData%\Mozilla\Plugins.
This folder isn't there by default, but can be created as a secondary folder to install a plugin like Flash for a specific user.
