Add-on?

[infertux]

What about making an add-on instead of fiddling with about:config by hand? Perhaps something similar to TorBirdy for Thunderbird? Thoughts?

It should be fairly straightforward using https://developer.mozilla.org/en-US/Add-ons/SDK/Low-Level_APIs/preferences_service

I won't do the addon myself, but I have experience with them. I'm available to help out via email/video call or whatever if needed.

I just came across #4 which may be a better fit for some users.

https://addons.mozilla.org/en-us/firefox/addon/random-agent-spoofer/ allows you to toggle privacy/security related settings.
edit: also https://github.com/TheCreeper/PrivacyFox

Nice! I found https://addons.mozilla.org/en-US/firefox/addon/tinfoil/ too.

For reference, see also prism-break/prism-break#1254 (comment) which requests the same thing, as well as https://github.com/RequestPolicyContinued/requestpolicy/issues?utf8=%E2%9C%93&q=is%3Aissue+is%3Aopen+preferences

I just developed an SDK based addon based on this list:
