The hidden Firefox preference :privacy.resistFingerprinting.block_mozAddonManager removes the WebExtensions restriction. Here is how you set it: 1 - Load about:config in the Firefox web browser. You can run a search for privacy.resistFingerprinting.block_mozAddonManager just to make sure it does not exist. It does not in the most recent Firefox Nightly builds at the time of writing. 2 - Right-click in the part of the window that lists the preferences, and select New > Boolean from the context menu. 3 - Name the new Boolean value privacy.resistFingerprinting.block_mozAddonManager. Set its value to true. A value of true means that WebExtensions work normally on Mozilla's website. You can undo the change at any time by setting the preference to false on the about:config page of the browser. Mozilla added the new hidden preference to Firefox 57. It is not available in Firefox 56, and there is no option to introduce it in the browser. Firefox Stable users who run WebExtensions right now need to wait until the browser is updated to version 57 to set the preference and gain the functionality

Before we bring new features to Firefox, we give them a test run to make sure they’re right for our users. To help determine which features we add and how exactly they should work, we created the Test Pilot program.

There is a huge selection of Firefox add-ons for tweaking privacy and security, some of the most popular of which are Adblock Plus and it’s many derivatives, NoScript, Flashblock, Ghostery, Web of Trust, BetterPrivacy, Lightbeam, Disconnect, Self-Destructing Cookies, Cookies Manager+, Request Policy, Policeman, Bluhell Firewall, RefControl, Smart Referer, HTTPS Everywhere and many, many others. With some possible exceptions, we won’t be using any of these, yet will retain much of the most important functionality offered by most of them with just a few add-ons, along with a plethora of changes to our Firefox configuration.

A giant table, I think it would be important to also include whether an old extension is no longer possible (deprecated), or someone just hasn't written an alternative yet, or whether there exists a planned API addition that would make it possible. Lots of alternatives are also missing a few features, and it would be good to know what's missing and why (impossible or just not yet implemented)The list is certainly not giant yet, but here's a start (based on responses from this post)/ https://www.reddit.com/r/firefox/comments/6i1fu2/webext_equivalents_to_legacy_addons/°

FIR 57 - ADDON - uBO/webext works best with Firefox 57 and above, and with multi-process enabled. There are many reports of people experiencing issues with some web sites, or images not loading, etc. Turns out many of these are a result of using some legacy extensions along uBO/webext. For instance, Reek's AAK in GreaseMonkey has been causing issues with images not loading. If you experience such issue, you will have to disable all your legacy extensions and see if this fixes your issue. If so, then you will have to re-enable your legacy extensions one by one to find the one(s) causing the problem. Those legacy extensions can cause multi-process to be disabled in your browser, and apparently when multi-process is disabled, this can cause many cases of page load failure.

Nightly Tester Tools is an extension that is a collection of useful tools for users of Firefox nightly builds. It was previously owned by Dave Townsend, but now is maintained by the Automation and Tools team. They're leading an effort to revive Nightly Tester Tools and make it even better. Nightly Tester Tools features the ability to disable add-on compatibility checks, crucial for nightly testers.
