I have firefox 56, but it keeps updating to firefox 57. Firefox 57 has severe performance related issues, and breaks my add-ons, and therefore I do not want it. Firefox 56 however seems to update against my will, and I want that to stop. How can I tell Firefox 56 to not update, not update without asking, or never look for updates.
I have not run sudo apt-get update, or sudo apt-get upgrade, but the NEW firefox keeps showing up.
Perhaps as a separate question, how can I tell apt-get to ignore new packages for firefox?
I have removed firefox and installed FF56 from source several times now, and it's getting obnoxious.
why is this thread different from the listed duplicates? well, firefox has an integrated updater, in the software that pushes new versions, independently of the Ubuntu OS package management system.
as an update, I figured out that by changing the "updater" executable in the source folder's name to "_updater", functionally prevents the unwanted update from occurring, although unwanted messages regarding an available update still occur.
sudo apt-mark hold firefoxas pointed above, or disable automatic security updates (bad idea). – Mateus Araújo Nov 21 '17 at 16:10
