7e18f8b473 tweak 2011
- FF85+ switched to using application regional locale
   - go to about:support > Internationalization & Localization (almost at the very end)
   - look at Application > Regional Preferences
- add test
2021-12-24 06:01:41 +00:00
d2510b014d move updates to personal
updating (app, extensions, ext cache) is not a privacy issue
- if you're willing to use Firefox but not trust updating, then I have two bricks to sell you: users who wish to disable it (to check changes first etc) and update in a timely manner, then that is on them - including any prompt fatigue
- same goes for extensions: the end-user installed them (and arkenfox only recommends a very select few) - the onus is on the end-user

The remaining ones I will deal with later

7811e912f4 make push notifications inactive
- they require SWers which are already blocked by virtue of permissions being session only
- also remove "dom.push.userAgentID" as this means prefsCleaner resets it and would wipe user's subscriptions
   - not adding "dom.push.userAgentID" to the cleanup script for the same reason

8860c90abf make service workers inactive
currently 3rd party service workers are blocked in FF95 when dFPI is enabled (which this version has should anyone update to 96-alpha)
   - but I get an error even on first party - https://arkenfox.github.io/TZP/tzp.html#storage

9d61992c8c don't clear offlineApps on shutdown, #1291
- in v94 we switched to cookies lifetime as session, so users could use site exceptions to retain selected cookies (to stay logged in one assumes)
- that mean not deleting all cookies on shutdown
- but some login methods/types require more than cookies and also need the "site data" part of "cookies + site data" - that's the offlineApps part
- note: all site data (and cookies) is still cleared on close except site exceptions

27977a16ad 2652: browser.download.alwaysOpenPanel
FYI: https://bugzilla.mozilla.org/1738372

There is a small privacy issue with shoulder surfers, but in reality, this just needs to happen IMO
- we already prompt where to save, but even if we didn't, we also know we clicked or initiated a download
   - unless it's a drive by or user-gesture trickery - which is why we prompt
- the download icon is shown (if hidden) and the throbber/accent color go to work
- users can always click the icon to show entries (and open folder etc)
- this maintains the current behavior in FF94

/***
This will reset the preferences that have been removed completely from the arkenfox user.js.
This will reset the preferences that have been
- removed from the arkenfox user.js
- deprecated by Mozilla but listed in the arkenfox user.js in the past
Last updated: 29-August-2021
Last updated: 9-February-2022
Instructions:
- [optional] close Firefox and backup your profile
- [optional] disable your network connection [1]
- start Firefox
- load about:config and press Ctrl+Shift+K to open the Web Console for about:config
- using about:config is important, so the script has the right permissions
- paste this script
- if you edited the list of prefs in the script, make sure the last pref does not have a trailing comma
- hit enter
- check the Info output to see which prefs were reset
- restart
- some prefs require a restart
- a restart will reapply your user.js
- [optional] re-enable your network connection
[1] Blocking Firefox from the internet ensures it cannot act on your reset preferences in the
period before you restart it, such as app and extension auto-updating, or downloading unwanted
components (GMP etc). It depends on what you're resetting and how long before you restart.

1. Consider using Tor Browser if it meets your needs or fits your threat model
* https://www.torproject.org/about/torusers.html.en
2. Required reading: Overview, Backing Up, Implementing, and Maintenance entries
* https://2019.www.torproject.org/about/torusers.html
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
