I have downloaded tar.gz file of the lastest firefox-quantum today.

I don't wish the old firefox to be replaced. Like the old firefox, I didn't find any single plugin especially the flash-plugin npapi installed in the quantum.

What should I do to enable/install the flash plugin for Firefox-Quantum?

PS: There's no plugin folder in the extracted files of the ffx-quantum otherwise I would've just moved the libflashplayer.so to the plugins folder!

    The installation procedure for plug-ins like Flash Player didn't change in Firefox Quantum. What changed is the removal of the interface for legacy add-ons which are not the same as plug-ins. – David Foerster Dec 30 '17 at 17:07

I found a solution

Just create a folder named plugins within the firefox/browser directory (i.e. in the extracted tar.gz of the latest version)

Move libflashplayer.so into the plugins folder you created

Now start Firefox (latest) and it will detect the npapi flash plugin.

Worked for me in Ubuntu14.04.5

PS - outdated Firefox still remains, which is no problem... for the time being
