Nearly no firefox vpn/proxy addon is working with this user.js

[Denio888]

It seems that no vpn/proxy addon for firefox which is not just changing firefox proxy settings is not working.

Which setting in the user.js could cause the vpn/proxy addons to stop working?
For testing i used the Cyberghost addon, but nearly all others are also not working.

Old issue #53 about this entry.

// PREF: Enforce Public Key Pinning

Thx for your reply.

It is sadly not the final solution, but perhaps part of the solution.
Still nearly no vpn/proxy addon is working when i set the Key Pinning to a value of 1 instead of 2.

Seems there are some more things left to change to get it working.

Same issue with Nordvpn. I tried to lower the pinning to 1 which didn't seem to work for me either.
I also tried to delete cert9.db and keep to 1 and then restart, didn't work either.

Same issue with Nordvpn.

Are you talking about this addon? How does it not work?

I took the liberty of making you a video easily showing my issues.
http://0x0.st/zJcq.mp4 (it seems to be on my end it says the video is corrupt, here it is in another format;. https://0x0.st/zJcc.gif) , also to note, when connected to the default, which seems to be US It completely stops all traffics and every single site is broken; NOTHING loads.

Leaving this here, the fix was simple. Disable OCSP.

user_pref("security.OCSP.enabled", 0);

Note that NordVPN does not use OCSP which is a security vulnerability.
