1. Consider using Tor Browser if it meets your needs or fits your threat model
|
|
|
|
|
* https://2019.www.torproject.org/about/torusers.html
|
|
|
|
|
2. Required reading: Overview, Backing Up, Implementing, and Maintenance entries
|
|
|
|
|
2. Read the entire wiki
|
|
|
|
|
* https://github.com/arkenfox/user.js/wiki
|
|
|
|
|
3. If you skipped step 2, return to step 2

4. Make changes

4. Make changes in a user-overrides.js

|
* There are often trade-offs and conflicts between security vs privacy vs anti-tracking
|
|
|
|
|
and these need to be balanced against functionality & convenience & breakage
|
|
|
|
|
* Some site breakage and unintended consequences will happen. Everyone's experience will differ
|
|
|
|
|
e.g. some user data is erased on exit (section 2800), change this to suit your needs
|
|
|
|
|
* While not 100% definitive, search for "[SETUP" tags
|
|
|
|
|
e.g. third party images/videos not loading on some sites? check 1601
|
|
|
|
|
* Take the wiki link in step 2 and read the Troubleshooting entry
|
|
|
|
|
5. Some tag info
|
|
|
|
|
[SETUP-SECURITY] it's one item, read it
|
|

[SETUP-WEB] can cause some websites to break
