Introduction (Windows and Linux related)
March, 2017
The NPAPI plug-in support has been removed from Firefox 52 (with the exception of Adobe Flash). Some of the plugins that will no longer load include Java, Microsoft Silverlight, Adobe Acrobat etc. In case you’re not yet ready for this to happen and require NPAPI plug-ins, Firefox Extended Support Release (Firefox ESR) will keep those plug-ins support enabled until May 2018.
As an alternative, you may install the Pale Moon browser. Pale Moon is an open-source browser forked from Firefox. It has the fully customizable interface similar to Firefox 28. Pale Moon uses Goanna engine, which is a fork of Firefox’s Gecko. A good number of Firefox extensions will work in Pale Moon thanks to its Firefox extension compatibility mode, though the two browsers are not the same, and sometimes you will have to check the list of add-ons with known compatibility issues and possible workarounds here: https://addons.palemoon.org/incompatible/ (Pale Moon will continue to support XUL and XPCOM based add-ons, contrary to Mozilla’s plan to deprecate them in Firefox 57.)
In the standard Firefox versions 52, 53 and 54 the user can turn on NPAPI plugin support using about:config (Nevertheless, please note that in Firefox 55 and later the ability to restore NPAPI plugin support has been removed completely.)
Here is how it can be done:

Set the plugin.load_flash_only option to false.
4.
Restart Firefox.

Profile
Please note that till version 56.x there is no need to export add-ons and bookmarks, as both versions may use the same profile, located in /home/user/.mozilla/firefox/ , named something like xyz0xyz.default
There are substantial changes in Firefox 57 profile. To use Firefox ESR 52.x and Firefox 57 Quantum intermittently you need to create separate profiles directories and edit your profiles.ini accordingly:
/home/user/.mozilla/firefox/profiles.ini
StartWithLastProfile=0
To start both versions simulateously use --no-remote switch:
Firefox --ProfileManager --no-remote
If Firefox Quantum messed up with your old add-ons, to bring them back, set in about:config to false the preference extensions.blocklist.enabled and, if neccesary, reinstall old versions of add-ons.
