Twitter is broken when PrivacyFox is enabled

[PLNech]

With PrivacyFox enabled, trying to follow someone or to like a tweet results in the following error message:

Disabling the extension is enough to make the error disappear, but it is quite cumbersome to toggle the extension every time I want to interact with Twitter. Is there a known workaround?

Try setting: network.http.sendRefererHeader to '1'
and network.http.sendSecureXSiteReferrer to 'true'

Thanks @Atavic, indeed when sending referer Twitter interactions work again.

@TheCreeper WDYT of this issue? Any plans to let users whitelist websites where referer is sent, or should we turn to another add-on for referer protection?

Twitter requires referer for login, but not for searching while not-logged. uMatrix, referer control and smart referer are some addons you could look at.
