User.js: request: paste your overrides

Created on 26 May 2018 · 25Comments · Source: arkenfox/user.js

so we can get a better handle on

what we could change in the default user.js
what users need to relax in order to get less breakage, or what they harden

Feel free to sanitize them before posting. I suggest ignore TP (tracking protection) and SB (safe browsing) overrides, since these will NOT be changed from default, and they're big lists of prefs

Here is the syntax for the collapsible content

<details><summary> name  overrides</summary><p>

you must have a line space above and below this and here
is where you put your ````js blah blah ``` stuff


</p></details>

What pref expires history by days?

With the way he wrote it, it should be clear that he's talking about an extension, mate ;)

earthlng on 29 May 2018

Yep, that's the one.

so six perps so far .. come on gals (and guys) ... @overdodactyl @Forsaked @grauenwolfe @Gitoffthelawn @Just-me-ghacks @RoxKilly @Theemim and co

If you don't actually use an overrides section, maybe just list a few of the items you don't use if you can remember them. TIA

some of Nikopol's overrides - the prefs for netflix is good. Definitely something for the relaxed version is to let audio and media run without issues

wow, I didn't ~~realize~~ remember that privacy.userContext.enabled was default false. ~~Mine's been true this whole time so I never picked up on it (I should use the prefs cleaner)~~ it's in my overrides, maybe its time to flick this to active

They're perhaps hesitant about enabling containers because a lot of people still don't even understand what Private Browsing does and doesn't do.

Is this something you guys do enough it would be handy to have an option in the scripts to just compare two files?

overdodactyl on 26 Nov 2018

^^ it outputs duplicated prefs (eg the parrots)

We already have :cat2: 's Compare tool, and that organizes the output way better. I just wanted to pull out what he relaxed, as that was his aim for end users in the reddit thread (I got the impression he wanted zero breakage).

If the updater script output a quick diff to preview that could be handy, but I think it's overkill. And I have no idea how hard it would be. :cat2: might be able to smash CompareUserJS into his updater, but then it might mean users need PS - IDK, not my area

PS: we do a Changelog issue

Thorin-Oakenpants on 26 Nov 2018

Just FYI, the updater.bat already requires PS because it uses it to instantiate a Net.WebClient object for downloading the user.js. It is the only way I know of to download files directly from a batchfile without having to install any third-party tools, and without relying on separate scripts in other languages like VBS. I still wouldn't smash Compare-UserJS into it, though. That wouldn't be pretty... :sweat_smile:

claustromaniac on 26 Nov 2018

@claustromaniac you could output a PK relaxed diff for us (just the items that we have active on and they have off or actively different)

Sorry, I know I'm not @claustromaniac, but I thought I would use this as a chance to test out the new updater script :)

Thanks @overdodactyl , but that's not a very good output for this purpose, its 350 odd lines including what we/they have that the other doesn't(?), I'm not sure, didn't look at it too hard, but I doubt there's 350 changes (ghacks user.js has 490 odd current prefs in total)

We just the items that we have active on and they have off or actively different... if our pref is inactive (and therefore at default) but they enforce a value, we ignore it, because we're not breaking anything here, we're at default. And in fact the values may be the same.
