network.trr.mode 3 keeps changing back to 2 which I have to manually change back
Hi Everyone,
network.trr.mode = 3 keeps reverting back to 2 after a while. I have to manually check and change the value back to 3, it could be after a few minutes or a few hours before the value reverts back to 2. How can I permanently set the value to 3? I am using Firefox 96.0.3, I have seen multiple posts about this issue with no solution from 2019 onwards. Is this a bug?
I am have multiple Firefox browsers 96.0.3 and this is occurring in each of them, which is really a hassle having to change each of them.

This article may help. From memory, it is possible to change the value of that preference. https://support.mozilla.org/en-US/kb/how-to-fix-preferences-wont-save
Do you use any add-ons related to network connections, proxy, or VPN?
Is your computer managed by an IT department?
If there are issues with the DNS service then maybe Firefox switches from TRR only mode (3) to TRR first mode (2).

No, add-ons vary depending on which PC I am using, the common add-ons are cookie auto-delete and ublock.
My computer isn't connected to a domain if that's what you mean if it's managed by an IT department?

I made sure the values of:
network.trr.custom_uri network.trr.default_provider_uri network.trr.uri
were all the same and followed some of the instructions in the article provided by TGNorth and it seems to have sorted itself out on all of the browsers apart from one where there was a slight difference in 2 of the fields where I did not append the ID for nextDNS logging, I must have forgotten to change it, the network.trr.mode reverted back to 2 on that browser.
Still keeping an eye on it.
