* reduce automatic connections to the minimum posible
## Considerations
This user.js is a fork from the arkenfox project with a substantial divergence. It tries to avoid all the automatic connections even though security could be reduced slightly.
For instance, OSCP is a privacy breach. Nevertheless, it is also a security feature. This user.js disables them as well as safebrowsing, automatic addons connections and so on. You will have to check manually addons updates in the related preferences section.
On the other hand, if you are using a GNU/Linux distro that connection could be removed unpacking two omni.ja files, removing all the addresses, and then re-zipping the omni.ja files.
`Unpack them` (do this for both of them separately):
mkdir unpack
mv omni.ja unpack
cd unpack
unzip omni.ja
`Remove telemetry`:
find -type f -print0 | xargs -0 sed -i 's/https\:\/\/firefox\.settings\.services\.mozilla\.com\/v1\/buckets\/main\/collections\/nimbus-desktop-experiments\/records//g';
find -type f -print0 | xargs -0 sed -i 's/https\:\/\/firefox\.settings\.services\.mozilla\.com\/v1\/buckets\/main-preview\/collections\/search-config\/records//g';
find -type f -print0 | xargs -0 sed -i 's/https\:\/\/firefox\.settings\.services\.mozilla\.com\/v1\/buckets\/main\/collections\/search-config\/records//g';
find -type f -print0 | xargs -0 sed -i 's/https\:\/\/firefox\.settings\.services\.mozilla\.com\/v1//g';
find -type f -print0 | xargs -0 sed -i 's/onecrl\.content-signature\.mozilla\.org//g';
find -type f -print0 | xargs -0 sed -i 's/remote-settings\.content-signature\.mozilla\.org//g';
find -type f -print0 | xargs -0 sed -i 's/normandy\.content-signature\.mozilla\.org//g';
`Replace the omni.ja files`:
mv omni.ja back.omni.ja
zip -0DXqr omni.ja *
mv omni.ja ..
Besides, take into account it makes a connection to aus5.mozilla.org in order to autoupdate itself so you'll also have to add it to your host list.
Alternatively, you could copy the folder `distribution` with the `policies.json` file into your Firefox installation folder. More information about this:
