Yeah, I confess, I still use Firefox. I'm so sick of the constant nags to update interrupting my workflow multiple times per day. I don't need a slop delivery so frequently.
I will update on my own schedule, not theirs.
Here's how to block the nags on Mac and Linux. It bypasses the standard UI and stops the browser from incessantly checking for updates.
Locate the Firefox Installation Folder:
Mac: Right-click Firefox in the Applications folder, select Show Package Contents, and go to Contents/Resources/
Linux: Usually /usr/lib/firefox/
Create a folder inside that directory named "distribution".
Create a text file inside that new folder and name it "policies.json".
Paste the following code into that file and save it:
{
"policies": {
"DisableAppUpdate": true
}
}
Restart Firefox. Go to Settings > General, there should be a message saying "Updates disabled by your system administrator."
Follow these instructions at your own risk.
