corroborator.enabled - flipped on (seen this before but I can't remember WTF it is)

791

Basically reads omni.jar on every startup to check its signature then report telemetry.

tartpvule picture tartpvule on 16 Mar 2020

^ thanks. Whatever "then report telemetry" means exactly, telemetry should be covered by the master switch (I'm not going to bother checking - feel free to do so yourselves), so we're fine to ignore the corroborator pref unless there is something else about it

It uses Services.telemetry.scalarSet, so I think the master telemetry switch covers it.
IMO, this "Corroborator" costs disk I/O even when telemetry is master off-ed, so I would still disable it, but that's me.

tartpvule picture tartpvule on 16 Mar 2020

IMO we don't need allowTabDetach nor the featurePolicy pref (but add the delegation pref)

While looking at privacy.dynamic_firstparty.limitForeign I saw that we missed a new value 5 for cookieBehavior (2701), added in FF69 (1547813)

The 2 new restrict3rdpartystorage prefs relax the ETP restrictions on storage for certain redirects, to reduce breakage. I assume this only applies if the cookieBehavior is set to 4 or 5 and therefore doesn't affect us since we block all 3rd party cookies and site data.
Reduced breakage is probably something that people who change the cookieBehavior pref appreciate and thus I think we can ignore these 2 prefs.

extensions.experiments.enabled allows DevEdition + nightly users to install Webextensions with "experimental" (ie custom) APIs. Irrelevant for Release users (unless they mod their omni.ja files)

^^ SGTM

earthlng picture earthlng on 25 Mar 2020

does the ^^ refer to the proposed tls deprecated

yes

does giggling mean it's OK?

what?

[the rest]

IDK and IDC, and frankly I don't want to do this anymore

what?

SGTM ... Silently Giggling To Myself .. but now I realize it's a version of LGTM (looks good to me)

IDK and IDC, and frankly I don't want to do this anymore

Just do what you can, there's no obligation. Even if you do nothing, that's OK - take care of number one first - you've done more than your fair share - so thanks.

I can do the changelogs - but what I can't do is the diffs (just do one at each final release if you can) - unless you can share your scripts / delegate that with someone. Without the diffs, it would hamper quality/knowledge. I would also miss your insights, but at least with diffs there would be other eyes on them.

Take care, and hoard that toilet paper (have you stocked up amo and guns yet?)

SGTM ... Silently Giggling To Myself .. but now I realize it's a version of LGTM (looks good to me)

oh, never heard/saw that one. I meant "sounds good to me"

the diffs (just do one at each final release if you can)

yeah I can do that

Take care

thanks mate, you too!

and hoard that toilet paper (have you stocked up amo and guns yet?)

haha, that was a joke, I'm not hoarding anything. No guns either. I'm not worried about the virus at all, only about what "The Powers That Shouldn't Be" will do with it.

found an awesome recommend read from Pocket

you faked that, right? really cool if it's real though

earthlng picture earthlng on 28 Mar 2020

I would drop the stuff in the brackets and add a "Currently applies to ..." on the 1st line.
