This issue description is a little vague.

I think it's a suggestion for something to do at each ESR update, since it's a Meta Firefox's net team is willing to keep for pref tiding.

As for network.http.http2.move_to_pending_list_after_network_change, the pref is already true in Firefox. So, I don't know if the OP meant disable instead.

The related Bug is Bug 1706377. I really see a reason to do anything to it, though.

This new feature is built on the already existing mechanisms to detect network changes. It shouldn't be relevant to us, since we're over Tor, but if we really don't want to do anything in case of changes, we should disable the entire feature.

I think it isn't disabled on desktop (there were some attempts on Android), as this functionality doesn't use network requests, but checks stuff in the OS (I think mostly the route to the default gateway, see the code neighboring 4855ec2b).

I would confirm the previous decisions about this.

Yes.

I had already looked at this issue and its patch (the phabricator URL is still in my browser history) while handling #43028 (closed).

Fun fact, the original reporter was rui because a VPN issue

One more reason to let it be.

I checked also the other prefs.

I think the only one relevant to us bug is Bug 1506194, which extends network.predictor.enable-prefetch to early beta, but we already set it to false.

I love that necko team has a meta called "necko-tech-deb".

We have a Technical Debt as well, we should use it.
