I'm not sure why I had this bookmarked

• FF95+ 1732792 use bypassProxy flag
  • FF94+ 1732388 add bypassProxy flag

¯\_(ツ)_/¯ why bother having prefs, just feel free to bypass the proxy u guys

[Thorin-Oakenpants]

Jee-Hex said

Add-ons Search Detection 2.0.0 is now baked into omni.ja (under omni.ja\chrome\browser\builtin-addons\search-detection\) like other built-in search extensions in FF95. Probably related to why FVD Speed Dial was recently banned from AMO.

I'm not sure why I had this bookmarked

Maybe because of this? FWIW in addition to RemoteSettings (1732792), UpdateService.jsm (1733994) and Telemetry (1733481) will also soon fail over outside the proxy. The failover system addon will then be deprecated (1738345).

[Thorin-Oakenpants]

re-opening, not for 95 changes, but to followup on network.proxy.allow_bypass

[Thorin-Oakenpants]

OK, that's what did me in: hidden pref - and although I looked, there it is almost at the bottom

@Jee-Hex
-so this eventually replaces the failover pref? And the same warning should apply (it involves security features)? I don't see (yet) how extensions fit into this (I guess that comes later)

how's this (it's a bit shit to be honest, any help would be appreciated)

/* 0706: disable proxy bypass for system request failures [FF95+]
 * Remote Settings, UpdateService, Telemetry etc being added in stages
 * [WARNING] This includes security features
 * [SETUP-CHROME] If you use a proxy and you're happy to skip potential security fixes if the proxy fails
 * [1] https://bugzilla.mozilla.org/buglist.cgi?bug_id=1732792,1733994,1733481 ***/
   // user_pref("network.proxy.allow_bypass", false); // [FF95+] [HIDDEN PREF]

[Jee-Hex]

so this eventually replaces the failover pref?

I am not exactly familiar with this but judging from this, this and this the two prefs are not connected.

Otherwise looks good to me. And the search detection thingy is not directly related to this pref - I probably should have posted that as a separate comment.

[Thorin-Oakenpants]

Thanks. Yup, I gathered the search thing was separate, and I don't see it as a concern - what does it actually do, I don't get it?

Anyway, I will post a commit for the above tomorrow, I need some zzzz

[Jee-Hex]

what does it actually do

Just a "security feature" that pings mozilla servers when it detects search engine redirects/ eTLDs changes. But that comment was more of a FYI than advocacy anyway.

[Thorin-Oakenpants]

Ah, OK. I thought it was something to do with hardening up detecting search engine changes and resetting them: I thought they wanted to get rid of system addons these days
