I wonder if you'll have to remember to do this after each update, like you have to do for most of Chrome's unwanted and unwelcomed features.
{
"policies":
{
"DisableAppUpdate": true
}
}
Create a text file named policies.json in a directory named distribution inside the Firefox installation directory. In my case that ends up looking like this: /opt/APPfirefox (package root)
/opt/APPfirefox/firefox (currrent nightly)
/opt/APPfirefox/bin/firefox-127.0a1 -> /opt/APPfirefox/firefox/firefox-127.0a1
/opt/APPfirefox/distribution/policies.json
The browser sees this file and abides by its contents. Open about:policies#documentation in Firefox to see which policies can be configured this way.[1] https://support.mozilla.org/en-US/kb/customizing-firefox-usi...
I had the settings disabled, then updated to the latest version ("126.0 (64-bit)") and settings were kept disabled.
So at least for now it looks like it respects your current settings.
