Non si può nascondere la notifica a meno di non bloccare completamente gli aggiornamenti -> https://turbolab.it/browser-455/come-impedire-firefox-aggiornarsi-3795

I found the method:

go here

1 https://ftp.mozilla.org/pub/firefox/nightly/partials/2024

2 download the last partials.mar

3 move it to /firefox/updates/0/ folder (re-name to update.mar)

Use the executable updater so ? Usage: updater patch-dir install-dir apply-to-dir [wait-pid [callback-working-dir callback-path args...]]

(to see the right update directories look at the old log files that firefox creates during the "standard" update).

Firefox will apply the last partial and will start. Logically, being incremental updates, the next update should be found. Jumping one or more partial updates you might run into problems. and safe it doesn’t work to rollback (downgrade). as far as l1on is concerned, I did not understand how it can work, since the incremental packages for Italian are four and all with the same date and time of creation... while for the update of the browser only the file is unique and it is easy to identify the next increment.
